Too less description!
I don’t know how to specify value to this variable to meet my needs
Packaging With CPack — Mastering CMake
Can I get a demo please!! Thank you very much 
!
How should I specify the pairs of directory and subdirectory, whether both directory can be specified with absolute path or I should specify the subdirectory in relative path, which will be relative to variable CPACK_PACKAGING_INSTALL_PREFIX? How to separate each pair?
Another question:
How can I generate both each-component distribution package and all-component distribution package by using DEB or TGZ generator, I have achieved generating deb package for each of my component by setting CPACK_DEB_COMPONENT_INSTALL to ON.
how to use CPACK_PROJECT_CONFIG_FILE for each of my package generator to specify variables for each generator exclusively?
Where can I get more examples about cpack?
Best wishes! I do really need your help, Thank you!
