[CMake] Newbie questions: verbosity and compiler invocation

Thanks. My situation is:

  ------ FolderA --- CMakeLists.txt
      |
      |- FolderB --- ErrorHandler.cpp

As FolderB is not beneath FolderA, I don't know how to specify FolderB/ErrorHandler.cpp in CMakeLists.txt using CMAKE_CURRENT_SOURCE_DIR. Do I need to set PROJECT_SOURCE_DIR to the parent folder of A and B?

Can you suggest how I can do this please?

Best regards

David
