Yes off course build dependencies may be distribution specific and
may not be found with executable/lib dep.

yes ok too.
For this the better we can do is to offer the user with a way to
manually specify thoses dependencies for each distribution he wants
to support.

Yes I understood that but in the CPackConfig file you may setup distro
specific deps from within generator specific case.
save the attached CPackConfig.cmake file in your project directory
then add
set(CPACK_PROJECT_CONFIG_FILE ${CMAKE_CURRENT_SOURCE_DIR}/CPackConfig.cmake)
in your main CMakeLists.txt then
rerun CMake
run CPack and see what happen.
I think that you'll see that it should suits your needs
since you may already customize the dependencies
in a distribution specific way for any CPack generator.
May seems weird but it should work.
This scheme supposes you are not "cross-packaging" like packaging
a Fedora RPM on a debian host.
