Thank you Yvan to contribute to RPM documented usage and feedback.

I shall add that we could add more sophistication into CPackRPM to make
it "search" for test.sh at different places:
    CMAKE_BINARY_DIR
    CMAKE_SOURCE_DIR
    etc ...
but currently it doesn't seem to be worth effort since specifying
absolute path is enough.
