In fact the DEFAULT directory, AFAIK, is not source root
but the working dir where you have launch cmake.

1) If it's your first build

    mkdir my_build_dir
    cd my_build_dir

    cmake /path/to/source_dir

     make

2) if you have already run cmake in "my_build_dir"

     cd my_build_dir
     cmake .


You may find some console/screenshot of such CMake
usage as we document it for our TSP software:

See §2.3 Source Installation.
