I installed googletest in WSL. I copied the gtest static libraries to /usr/lib. And then moved gtest and gmock folders to /usr/local/include/.

I am working on a library. That library internally is broken into folders with related modules. Each folder has its own unit tests. At the root of the library I want to make a single CMakeLists.txt file that builds all the unit tests for the entire library. Ideally I dont want to directly reference every source file in the main CMakelists.txt, but instead include each of the modules tests.

I have the following project structure:

I have a problem with running gtest using cmake. This started after I changed the project structure, dividing the code into several modules with separate CMakeList.txt files. When I had one CmakeList without a static library, everything works fine.
