It looks like your get default "/usr/local" prefix from somewhere.
The installation prefix of CPack is controlled by the
https://cmake.org/cmake/help/latest/variable/CPACK_PACKAGING_INSTALL_PREFIX.html
variable.
Each CPack generator has a default value for that (if you don't specify it).

How do run cpack?
Do you do "make package" or do you run
cpack -G DEB

Which version of cmake/cpack are you using?

DEB generator is not as verbose as I thought.

Do you generate RPM as well? RPM is more verbose and leaves you log file in
_CPack_Packages/<yoursystem>/RPM/

Is the RPM containing what you expect?
