Encountering Issues Building for Apple M1

[jstr045329]

I'm new to gtest so sorry if this question is dumb.

I think my project is building successfully, but I keep getting this error:

/Applications/CLion.app/Contents/bin/cmake/mac/aarch64/bin/cmake --build /project/dir/MyProject/cmake-build-debug --target all -j 6

Looks like the GoogleTest library isn't being linked. The linker is trying to create your executable with only gtest_main.cc.o, but it's not linking against the actual GoogleTest library that contains the implementations of InitGoogleTest() and UnitTest::GetInstance().

GoogleTest needs gtest_main.cc and the actual GoogleTest library implementation

You can probably try to integrate GoogleTest into your CMake project with add_subdirectory().
