While running the cmake's script, I would like to obtain the path to the main build folder, which one chooses, for example in CMake Gui via "Where to build the binaries" text input.
Best match that I have found so far is the PROJECT_BINARY_DIR variable, that unfortunately gets you the folder: ./build/modules/project_name.
I would like to get the .../build folder only.
I know I can extract .../build from .../build/modules/project_name with some hacking but would anyway like to get the .../build directly!
