GoogleTestAddTests.cmake:112 - Error running test executable (result 164)

[Ashe]

Hello everyone, I've been adding some stuff to my CMakeLists.txt file today and have broken my unit tests, but I don't know why.

Here's my MakeLists.txt: https://gist.github.com/Ashe/b75eb84e59e01bfd4b283877b53a50c0

The offending line is gtest_discover_tests(unit_tests). Removing this makes things work, but the unit_tests executable does nothing when ran.

Here's the build output when trying to use gtest_discover_tests:

[ 43%] Built target cimgui
[ 43%] Built target sokol

make[1]: *** [CMakeFiles/Makefile2:986: CMakeFiles/unit_tests.dir/all] Error 2
make: *** [Makefile:146: all] Error 2

I can't find anything online about what the error code of 164 actually signifies. Some discussion online talks about some project files that aren't related to the build, but the new files I've generated that I add to my library are used in the project, just not in the tests.

If I remove the link to ${LIBRARY_NAME}, my tests compile as normal (I don't have non-trivial tests yet), so it must be something to do with the connection between my library and the tests.. if only I knew what 164 meant!

I hope someone can give me some help or even a place of error codes I can go check?

Thanks!

Fixed by recloning my project, weird one.
