URL_HASH
mismaches cause the download to be retried a few times in a row, with fixed sleep intervals in between. The lack of output during this time makes CMake look like its hanging. After about 2 minutes CMake terminates the configuration and prints all the download errors. These errors should ideally be printed while they happen so it doesn't look like its hanging.
Here is the example package with an invalid hash to reproduce my issue.
CPMAddPackage(
NAME SDL2
VERSION 2.0.12
URL https://www.libsdl.org/release/SDL2-2.0.12.zip
URL_HASH SHA256=f
)
Here is the output at which CMake seems to hang:
-- CPM: adding package [email protected] (2.0.12)
Libraries using CPM should already work in a hunter / conan / vcpkg package without modification, however they will always re-build dependencies even if they are already installed by the package manager. It should be possible to detect when the library is being installed by a package manager. In that case CPM should try to fetch the package with the package manager before downloading and building from source.
Perhaps additional arguments like CONAN_NAME
etc. to CPMAddPackage
can be used to specify the package manager parameters.
Hello,
I'm using CPMFindPackage() to check for a dependency on CMocka and noticing some strange behavior with the find_package

Module in question
https://github.com/martell/pthreads-win32.cmake/blob/master/CMakeLists.txt
This is a cmake adaptation on top of the original pthreads-win32 library. The original library has header/source file in a single directory.
The cmake adaptation makes proper install targets and move the header/complied libs into the proper location (see below)
install(TARGETS ${PTHREADS_LIBRARY}
RUNTIME DESTINATION ${PTHREADS_BINDIR} COMPONENT ${PTHREADS_BINCOMPONENT}
LIBRARY DESTINATION ${PTHREADS_LIBDIR} COMPONENT ${PTHREADS_LIBCOMPONENT}
ARCHIVE DESTINATION ${PTHREADS_LIBDIR} COMPONENT ${PTHREADS_LIBCOMPONENT}
PUBLIC_HEADER DESTINATION ${PTHREADS_INCLUDEDIR} COMPONENT ${PTHREADS_INCLUDECOMPONENT})
When adding this library using CPMAddPackage(), I needed to do something like
target_include_libraries(TARGET INTERFACE <PATH_TO_SOURCE_DIR>)
This adds all .h
files as include headers, not just the public header.
My understanding is that CPM does not trigger the "install" step, but just the "configure/build" steps when adding a package.
Is there anyway to only include the public header?
Thank you!
Here's how I am adding that library via CPM

I want to use CPM at my company but I'm concerned about the following types of scenarios. That could easily occur if every project is individually downloading CPM.
Project A uses CPM 0.27.5
Project B uses CPM 1.01.0
Project C uses CPM 0.10.0
What happens if project A uses project B?
What happens if project B uses project A?
What happens if project B uses project C?
What happens if project C uses project B?
I need to pass HTTP_USERNAME and HTTP_PASSWORD parameters as variables like this:
CPMAddPackage(
NAME headers
URL https://<my URL here>file.zip
HTTP_PASSWORD ${NEXUS_PASSWORD}
HTTP_USERNAME ${NEXUS_USER}
)
It works fine when I hardcode username and password but doesn't work when I use variables. Please help.
Hi @TheLartians ,
Thanks for the library.
When I include a CMake library with CPM.cmake it runs all the install commands in that library even when I don't need these installers with my own library.
When adding the library as a subdirectory, it's possible to use add_subdirectory(libname EXCLUDE_FROM_ALL)
to avoid that behavior.
Is it possible to use EXCLUDE_FROM_ALL when downloading a CMake library?
I don't know if that's a question or an enhancement.
Best,
I have the following setup, with NEWLIB and its dependency jegp both depending on range-v3.
Having translated directly from a sequence of FetchContent
s and accompanying FetchContent_MakeAvailable
to a sequence of CPMFindPackage
, jegp is first found and finds range-v3, but when NEWLIB does it, DOWNLOAD_ONLY
is ""
, as seen in the error below, for which I used cmake_print_variables
.
Running /usr/bin/cmake -GNinja <source-root>/newlib in <source-root>/newlib/build.

I have circumvented this by first declaring my direct dependencies for which I know my other direct dependencies depend upon, which is necessary since the content is immediately made available, but it could become a nightmare in more complex scenarios.
Currently CPM.cmake requires CMake 3.14, as specific used FetchContent
features are only available in recent versions of CMake. Theoretically, it should be possible to support older Versions of CMake by downloading the FetchContent.cmake script on-demand for old CMake versions.
As mentioned in TheLartians/ModernCppStarter#61 (comment) I would like to know if it's right for the libraries to not be made available as SYSTEM libraries?
Including as SYSTEM would mean that warnings set for the project using CPM would not falsely warn for code in 3rd party headers.
Currently GIT_TAG
defaults to v(VERSION)
, which is the versioning convention many Git projects use, but not all. Is there a portable and efficient way to detect or find git-tag based versioning schemes?
Dont know if I need to create an issue link with the pr #164 .
The issue is when you work with cmake and never install package on host, i.e when developing for embeded device.
This is a fix extract the version from the target itself if possible,
I use that since we work with multiple lib for embedded prog.
In each lib we just had to set the Properties Version
I just put that at the end of all package I made:
get_target_property(_TARGET_TYPE ${PROJECT_NAME} TYPE)
if(_TARGET_TYPE STREQUAL "INTERFACE_LIBRARY")
set_target_properties(${PROJECT_NAME} PROPERTIES INTERFACE_VERSION ${PROJECT_VERSION} )
else()
set_target_properties(${PROJECT_NAME} PROPERTIES VERSION ${PROJECT_VERSION} )
endif()
with that the PROJECT_VERSION is the version selected by CPM.
It should be possible to use short github identifiers instead of full url as in cget. For example instead of
Just write
jgm/cmark
I understand the usage but documentation is missing on how to make my projects useable with CPM:

I'm tryiing to build ydotool which is a package using CPM.make. This is for fedora and they do not allow builds using in-build downloads - I have to provide a versioned tarball including all the dependencies.
ydotool has several dependencies including IODash
I'm trying to use -DCPM_IODash_SOURCE=/path/to/source but I always get the error:

I'm trying to use Howard Hinnant's date library with CPM.
This works:
CPMAddPackage(
NAME HowardHinnant_date
GITHUB_REPOSITORY HowardHinnant/date
VERSION 3.0.0
)
But I have to use #include "include/date/date.h"
to include the header. I want to get rid of the include
part in the #include
path (#include "date/date.h"
).
I tried
if(HowardHinnant_date_ADDED)
target_include_directories( HowardHinnant_date INTERFACE
${HowardHinnant_date_SOURCE_DIR}/include )
endif()
But cmake complains that target HowardHinnant_date
is not build in my cmake project. So I changed this into (using the actual target's name (e.g., myproject
))
if(HowardHinnant_date_ADDED)
target_include_directories( myproject INTERFACE
${HowardHinnant_date_SOURCE_DIR}/include )
endif()
But still the pre-processor cannot find date/date.h
in #include "date/date.h"
.
I use similar dependencies for various project, so that new feature would help me a lot. Is there a way to setup an environment variable for it? I would set CPM_SOURCE_ROOT
per machine/user not per project. I would point in to $HOME/.cache/CPM
or similar
CPMAddPackage(
NAME SDL2

add_executable (test "main.cpp" )
set_target_properties(test PROPERTIES CXX_STANDARD 20)
target_link_libraries(test SDL2)
I get an Error LNK1104 cannot open file 'SDL2.lib'
, SDL2.lib does not exist, it was not compiled.
Building with the shared library compiles fine.
I want to affect the scope from which CPMFindPackage
is called to append the package's source directory to CMAKE_MODULE_PATH
, as they contain my project's CMake modules. With FetchContent
it is possible, as FetchContent_MakeAvailable
(apparently a macro) eventually calls add_subdirectory
.
The CMake modules repository CMakeLists.txt
is
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}")
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} PARENT_SCOPE)
Before realizing this was possible, I just included its first line after the FetchContent_MakeAvailable
call.
As I understood the documentation, I should be able to configure a cmake project with CPM packages without internet access as long as the I am using a local cache and it contains the package in the version needed.
One question I have about this: when I specify GIT_TAG master
how does it know if the cache is still valid without checking online?
When I try to use it that way without internet access, it actually fails somewhere in the FetchContent
module while trying to access the online repository. (I checked the cache is active, populated and CPM shows it is finding a cache entry).
So the "offline" mode only works if you specify a commit hash? Would be good to add this to the documentation I think.
Hi,
Let me preface this issue report with a huge congratulations. I love cpm.cmake, it solved a lot of dependency management I had with using cmake. and I am working on porting over my build system to use cpm.cmake exclusively.
I ran into an issue while using cpm.cmake with duplicate target names by trying to add two child cmake packages.
To reproduce:

The error I get when I run cmake:
CMake Error at cmake-build-debug/_deps/eigen-src/blas/CMakeLists.txt:15 (add_custom_target):
add_custom_target cannot create target "blas" because another target with
the same name already exists. The existing target is a static library
created in source directory

I can work around this issue by setting a CMake option to pick one or the other, but was wondering if there's a way to add "namespace" to target names to avoid this from the package manager itself?
Some repositories don't prepend their tags with vx.y.z
But CPM automatically adds the v, so it makes some repositories not work.
If CPM_SOURCE_CACHE
is set to an empty string, CPM fails with file DOWNLOAD error: cannot create directory '/cpm' - Specify file by full
.
Create a chat room on Gitter would be a great way of asking and answering questions, and discuss in general!
When I active the CPM_SOURCE_CACHE, I get a subcommand failed error. It appears to be originating from this line.
executing:
cmake -B_build -GNinja -DCMAKE_TOOLCHAIN_FILE="../../cmake/arm-gcc-cortex-m4.cmake" -DCPM_SOURCE_CACHE="C:\Users\ryanw/.cpm"

CPM adds a v
to the version tag
which results in:
CMake Error at glfw-subbuild/glfw-populate-prefix/tmp/glfw-populate-gitclone.cmake:40 (message):
Failed to checkout tag: 'v3.3.2'
Because glfw does not prefix it's version tags with v (https://github.com/glfw/glfw/tree/3.3.2).
Some projects don't use the 'v' when tagging. CPM.cmake assumes/adds a 'v' in front on the tag for VERSION. Perhaps it should just use what it is given?

Hi, thanks for developing the very nice tool. I like the snippet in the Wiki page, Downloading CPM.cmake in CMake, which makes it easy to set up CPM in my project just by adding a few lines.
But I was wondering that the downloaded CPM could be also stored in the cache specified by CPM_SOURCE_CACHE
. Indeed, the following seems to work:
set(CPM_DOWNLOAD_VERSION 0.27.2)
if(DEFINED ENV{CPM_SOURCE_CACHE})
# If CPM_SOURCE_CACHE is given, then use the cache directory also for CPM.
set(CPM_DOWNLOAD_LOCATION "$ENV{CPM_SOURCE_CACHE}/cmake/CPM_${CPM_DOWNLOAD_VERSION}.cmake")
else()
set(CPM_DOWNLOAD_LOCATION "${CMAKE_BINARY_DIR}/cmake/CPM_${CPM_DOWNLOAD_VERSION}.cmake")
endif()
if(NOT (EXISTS ${CPM_DOWNLOAD_LOCATION}))
message(STATUS "Downloading CPM.cmake")
file(DOWNLOAD https://github.com/TheLartians/CPM.cmake/releases/download/v${CPM_DOWNLOAD_VERSION}/CPM.cmake ${CPM_DOWNLOAD_LOCATION})
endif()
This gives a benefit that repeating downloads of CPM.cmake can be also avoided, and one can create new builds offline if CPM and all dependencies are cached. The disadvantage I can see is only that one needs the 4 additional lines in CMakeLists.txt
.
Do you see any problem with using a cached CPM.cmake in the above way? I just checked with a small test, so maybe I missed something.
If the above has no problem, then perhaps putting it in the Wiki page would be a good idea, maybe in addition to the original simpler one, if you like.
Hello, I was wondering what the differences really are between using CPM.cmake and just native CMake FetchContent functions? For me it seems that the benefits of CPM.cmake, those that are listed on the README, are actually benefits of FetchContent for the most parts. It seems that the "versioning" talked in documentation is the same as provided by FetchContent --- basically just referencing to particular commit hash or version tag.
set(PACKAGE_NAME cxxopts)
FetchContent_Declare(${PACKAGE_NAME}
# Compared to release tag or branch, commit hash avoids network connection
# if the local clone already has that particular commit.
GIT_REPOSITORY https://github.com/jarro2783/cxxopts.git
GIT_TAG e6858d3429e0ba5fe6f42ce2018069ce992f3d26 # tag v2.2.0
)
FetchContent_MakeAvailable(${PACKAGE_NAME})
# What are the differences to CPMAddPackage here? (Aside from `OPTIONS`)
CPMAddPackage(
NAME ${PACKAGE_NAME}
GITHUB_REPOSITORY jarro2783/cxxopts
VERSION 2.2.0
OPTIONS
"CXXOPTS_BUILD_EXAMPLES Off"
"CXXOPTS_BUILD_TESTS Off"
)
We can set cache path for both methods: FETCHCONTENT_BASE_DIR
for FetchContent and CPM_SOURCE_CACHE
for CPM. It seems that setting FETCHCONTENT-variables will also effect behaviour of CPM.cmake script. Setting FETCHCONTENT_FULLY_DISCONNECTED
will also disable CPM packages and result configuration step working significantly faster.
Also notice the comment about using commit hash compared to version tag. I read somewhere that commit hash will perform faster check (probably on Professional CMake book).
Second thing. I tried to understand how the OPTIONS are passed to FetchContent internally in CPM.cmake script. May you enlighten me how can you do that actually? There is no mention about passing variables in CMake documentation like that. I will show example of how I have understood how "passing" the options works for FetchContent. The downside is that if those variables would effect other dependencies, then you need to unset them after adding the dependency.

endif()
# *****************************************************************************/
In above, rather complex example, we need to use add_subdirectory
combined with add_library
call made by the actual dependency's CMakeLists.txt, which names the main target as utf8cpp
. This is due we want to pass CMake options and C++ compile definitions for the target.
Hello,
In commit ab7000d the set(CPM_ARGS_VERSION 0)
was removed.
So when cpm cant find the version from a package there will be no default version number.
Was there any issue with this setup?
It was useful to compare between two cpm of the same package.
Specifying DOWNLOAD_ONLY
in CPMAddPackage
or CPMFindPackage
seems to be configuring the package.
Not sure if this is a CPM bug, or if I've misunderstood the behavior when DOWNLOAD_ONLY
is present.
For example, this starts configuring the libcu++
LLVM tests:
cmake_minimum_required(VERSION 3.18 FATAL_ERROR)
project(LIBCUDACXX_CPM_TEST)
# Uses CPM v0.27.5
include(get_cpm.cmake)
CPMAddPackage(NAME libcudacxx
VERSION 1.4.0
GIT_TAG 1.4.0
GIT_REPOSITORY https://github.com/NVIDIA/libcudacxx.git
GIT_SHALLOW TRUE
DONWLOAD_ONLY TRUE
)
take a full URL to the git repo
The caching aspect was the main reason I tried to give it a try but it doesn't seem to be working. Based on the title, is there something I'm missing about how this is supposed to work?
Hey there!
I successfully adopted CPM in my project, helping me to avoid 4 GB big repos being checked out everytime I change configuration or clear the cache. Which, by itself is pretty neat.
However, I recognized, that CPM pollutes my targets with files from other projects. See the following screenshot:
Yes, I had to censor the target and project names in order to avoid trouble at my work place. The two folders I marked with the red arrows contain files exclusively from other targets.
Interestingly, this happens only for targets that either:
GITHUB_REPOSITORY
option)Is there a way to prevent this?
Looks like I completely misunderstood the semantics of target_sources
in combination with PUBLIC
.
Because I inherited an old project and there's a lot of dependencies, I don't really have a say in whether to include them or not.
Right now when I make any chanegs to the CMakeLists file, reconfiguring the cmake project literally takes like 5 mins to finish. This is largely because of CPM calling "configure" on a few old projects that do a lot of testing of different headers / platforms.
Would it be possible to mark a project as "CACHED" to configure it only once at the first load and just skip it in subsequent configure
s?
i.e. this is an example output I have for one such "configure" step, majority of the dependencies are never changing, so i don't think there's any need to reconfigure them

Hi, is it possible to use CPM to include and build Boost, or do packages need to follow good CMake practices? Can you use something like:
CPMAddPackage(
NAME boost
GITHUB_REPOSITORY boostorg/boost
VERSION 1.70.0
GIT_TAG boost-1.70.0
)
if (boost_ADDED)
add_library(boost INTERFACE IMPORTED)
target_include_directories(boost INTERFACE "${boost_SOURCE_DIR}/include")
endif()
target_link_libraries(asio-test PRIVATE boost)
CPM currently clones full history for git-repository dependencies, which takes more time than necessary (in most cases) on downloading, and consumes more disk space.
Maybe use git shallow clone by default for those dependencies?
There is a GIT_SHALLOW
option to enable --depth=1
with clone, which does what we exactly desire.
If I may, I would like to make a PR on it, :-)
Hello, first thanks for your work, it is very good and helps me a lot in my projects.
I think that including a manifest as a way to download dependencies would be an incredible resource for this project, as it will improve the organization and readability of the projects that use it as a package manager.
I'm having a hard time using CPM with the SDL2 libraries.
I've used the ModerCppStarter repository to start this project.
Adding SDL2
works fine:
CPMAddPackage(
NAME SDL2
VERSION 2.0.12
URL https://libsdl.org/release/SDL2-2.0.12.zip
)
But I can't make TTF
and Mixer
libraries to work as intended:
CPMAddPackage(
NAME SDL2_ttf
VERSION 2.0.15
URL https://libsdl.org/projects/SDL_ttf/release/SDL2_ttf-2.0.15.zip
DOWNLOAD_ONLY TRUE
)
CPMAddPackage(
NAME SDL2_mixer
VERSION 2.0.15
URL https://libsdl.org/projects/SDL_mixer/release/SDL2_mixer-2.0.4.zip
DOWNLOAD_ONLY TRUE
)
...
add_library(PacMan ${headers} ${sources})
target_include_directories(PacMan
PUBLIC
$<BUILD_INTERFACE:${SDL2_ttf_SOURCE_DIR}>
)
target_include_directories(PacMan
PUBLIC
$<BUILD_INTERFACE:${SDL2_mixer_SOURCE_DIR}>
)
...
target_link_libraries(PacManStandalone PacMan cxxopts SDL2 SDL2_ttf SDL2_mixer glm)
When linking the SDL2_ttf
and SDL2_mixer
libraries to the project, in the CMakeLists.txt file of the standalone source, I've get the following error:
[ 47%] Built target SDL2
[ 51%] Built target PacMan
[ 51%] Linking CXX executable PacMan
/usr/bin/ld: cannot find -lSDL2_ttf
/usr/bin/ld: cannot find -lSDL2_mixer
/usr/bin/ld: cannot find -lSDL2::SDL2
/usr/bin/ld: cannot find -lFreetype::Freetype
Apparently, I need to build the SDL2_ttf and SDL2_mixer linking to the SDL2 target, but I have no clue of how to do that.
Thanks in advance.
When setting CPM_SOURCE_ROOT
to an external directory, CMake will initially erase existing repositories and try to re-download them. This breaks the purpose of the feature.
Hello, firstly thanks for the awesome package manager you made. I had a great time using this in some of my projects.
But I think a more advanced versioning feature like npm is essential for a package manager.
I think having this would be a great improvement for CPM. Would you like to have a look into it?
Thanks a lot in advance!
The cpm_parse_option
function fails if the list of options don't follow the key/value format. I discovered this with the following code:
CPMAddPackage(
NAME googletest
GITHUB_REPOSITORY google/googletest
GIT_TAG release-1.8.1
VERSION 1.8.1
OPTIONS
"INSTALL_GTEST OFF"
"gtest_force_shared_crt ON"
"GTEST_HAS_STD_TUPLE"
)
Error message: string begin index: 20 is out of range 0 - 19
on line 196 of CPM.cmake
.
The issue goes away if you do the following instead:
CPMAddPackage(
NAME googletest
GITHUB_REPOSITORY google/googletest
GIT_TAG release-1.8.1
VERSION 1.8.1
OPTIONS
"INSTALL_GTEST OFF"
"gtest_force_shared_crt ON"
"GTEST_HAS_STD_TUPLE ON"
)
Has CPM been tested with internal GitHub repositories?
My company will be switching to GitHub soon and obviously the repos aren't public.
So I'm curious how CPM works with internal repositories.
How does one go about signing/securing things? IE security problems.
If this is already possible and I didn't realize perhaps an explicit entry in the Wiki would be greatly beneficial.
suppose I have a private gitlab repo that I can clone with this command (SSH):
git clone [email protected]:my-team/my-project.git
how do i do it with cpm?
it seems that cpm.cmake GITLAB_REPOSITORY want a https clone command
Currently CI tests are done by running all example script on a Linux system. It would be great to extend tests to the the Windows and Mac platform as well. The main issue here is supporting C++17 on travis builds, as the examples depend on it.
I've added some prettify to the cpm_add_to_package_lock and cpm_add_comment_to_package_lock.
It's in PR #162
Hi, for us at the more beginner state that wants to contribute or make our projects more compliant with CPM you have the wiki that states what needs to be added. However, I still struggle a little with it. So I was curious if you were interested in adding a minimalistic library example?
