[CMake] Automatic regeneration of software packages by CPack?

[SF Markus Elfring]

Hello,

I configured a specific software to use the CPack modules to generate
corresponding DEB and RPM packages together with CMake 3 a while ago.

I notice now that package specifications and control files contain
outdated version data after I called the command "make package".
How can I achieve that another build dependency is automatically
considered there?

Regards,
Markus
