Hi,

Please try placing https://github.com/Yixin-Hu/TetWild/blob/master/CMakeLists.txt#L123-L135 with

add_executable(new_gtet ${SOURCE_FILES})
target_link_libraries(new_gtet geogram igl::core igl::cgal)

Can you please post the exact commands you are using to run cmake and make, and the detailed cmake output your are getting? I don't seem to have any problem on Ubuntu.

I have double checked, I am able to build TetWild master branch out of the box on a clean slate Ubuntu 18.04 with the following commands:

$ apt-get update
$ apt-get install gcc g++ cmake git libcgal-dev
$ git clone https://github.com/Yixin-Hu/TetWild.git
$ cd TetWild/
$ git submodule update --init --recursive
$ mkdir build
$ cd build/
$ CC=gcc CXX=g++ cmake .. 
$ make
$ ./TetWild --input <input_mesh> --output <output_mesh>

I don't know what was the problem before but now cmake runs with no issue. But when trying to make it, having a lot of error starting like this

                 from /usr/include/CGAL/Constrained_Delaunay_triangulation_2.h:25,

I have followed the instruction given here

but, having the same error.

Your cmake seems to find Ubuntu’s CGAL ( as you can see, errors point to /usr/include/... ).

Maybe uninstall Ubuntu’s CGAL, and try again.
