Somebody some time ago decided on concrete paths and if I try to change it, I got into real trouble. All our tools have hardcoded paths, many things have dependecies on source or build directory location.

Yes there is.

CPACK_PACKAGE_DIRECTORY is what you are looking for.
see: cpack  --help-variable CPACK_PACKAGE_DIRECTORY

You can set this variable in your CMakeLists.txt or CPack project config file or from the cpack command line using the "-B" command line option.

see: cpack  --help
