    Building in the source directory is not supported. Instead, you should
    create another directory specifically for the build. For example:
    
    mkdir ~/build/corinthia
    cd ~/build/corinthia
    cmake -G \"${CMAKE_GENERATOR}\" ${CMAKE_SOURCE_DIR}
    
    Before this will work, you should delete CMakeCache.txt and
    the CMakeFiles directory that were just generated in the source
    directory.")
