Could you provide the CMake output? Probably it's not being able to create the executable due to some issue with gmock.

Please clean the workspace and run it again, otherwise cmake is not re-executed and we cannot see the meaningful output.

This is the output of a brand new workspace that I
- built being empty
- cloned
ddynamic_reconfigure - built again (output supplied)
If I run catkin clean -y and catkin build again I get the same output. The log is to be found here.

Ok, please build it with -v to get some more output.

Looks like it couldn't find pthread. Looking at installed packages I find only libpthread-stubs0-dev being installed on my system.
I executed rosdep install --from-paths src --ignore-src --rosdistro=melodic -y before though - shouldn't that take care of all the dependencies?

I've got the same output regarding to pthread.
Can you try to find your gmock installation?
In my case:
$ dpkg -S gmock.h
googletest:amd64: /usr/src/googletest/googlemock/include/gmock/gmock.h
googletest:amd64: /usr/include/gmock/gmock.h
$ dpkg -S gtest.h
googletest:amd64: /usr/include/gtest/internal/custom/gtest.h
googletest:amd64: /usr/include/gtest/gtest.h
googletest:amd64: /usr/src/googletest/googletest/include/gtest/internal/custom/gtest.h
googletest:amd64: /usr/src/googletest/googletest/include/gtest/gtest.h
And my googletest version is 1.8.0-6

That's weird.
I'm insisting so much on gmock, because I've seen this behavior before. If gmock is not found, the target is not added (see this) and the target_link_libraries fails.
You could try to add some debug statements in /opt/ros/melodic/share/catkin/cmake/test/gtest.cmake to see if this is the case.

It builds on my other 18.04 machine, so it seems to be something in the configuration of my laptop which I couldn't find up to now. Even reinstalling ROS and setting up the workspace didn't work.
Here's the output of /home/matthias/Workspaces/ddynamic_reconfigure_ws/logs/ddynamic_reconfigure/build.cmake.000.log for the two machines.
But it doesn't look like it's something specific to ddynamic_reconfigure, but more a catkin configuration issue.
The crucial difference for me seems to be the order in which it runs through packages on the laptop vs the workstation.
Also the CMAKE_PREFIX_PATH looks wrong on the laptop, but the happens even with catkin clean and catkin config or catkin_tools/profiles/default/config.yaml are the same on both machines.

It looks like in your working version gmock is found
^[[36m--^[[0m Found gmock sources under '/usr/src/googletest': gmock will be built
and in the not working
[36m--[0m Found gtest: gtests will be built
Only gtest is found.

I screwed up to name the links -.- I renamed them now by editing the original post.

I don't understand your last message, which links?

In #6 (comment) I mixed up the pastebin links and the naming of the links. The link with the name "working" was linking to the "not working" output on pastebin. So I fixed the naming of the links by editing the comment.
In the mean time I played around with /opt/ros/melodic/share/catkin/cmake/test/gtest.cmake.
Turns out that both the statements if(NOT GMOCK_FOUND) and if(NOT GTEST_FOUND) around line 290 are satisfied on the machine that can build it.

I also compared all packages installed on both machines and I didn't find find any differences for any gmock, gtest packages or so.

Well, after a bit of more digging it turned out that /opt/ros/melodic/share/catkin/cmake/test/gtest.cmake would search for gmock, doesn't find it and searches for gtest. If there's still no success there seems to be some manual stuff. Here it becomes interesting:
- On the workstation it doesn't find
GTEST_LIBRARY GTEST_MAIN_LIBRARYand goes into aelsein the ROSgtest.cmakewhere this seems to be done manually - that works - On my laptop it finds
gtestsince there's at least/usr/lib/libgtest.a(which dpkg doesn't know about and neither do I) and then it fails later on.
Well, anyhow. It's not connected to ddynamic_reconfigure, so I will close this. I settled upon moving /usr/lib/libgtest.a since I don't know where it comes from anyway and now it builds on my laptop as well. Thanks for the help.

Wow that was a tricky one. Good job finding it.
