[CMake] CPack and user .spec file

Can this not be done from CMakeLists.txt by setting some additional CPACK_*
variables depending on the build environment?

Not certain what exactly you're doing here - while creating binary packages
Source directive is not used (CPackRPM is always the build driver so the
build phase of rpm is skipped and instead the CPackRPM prepared/built files
are used directly). Are you trying to produce a binary or a source rpm?

If the answer is binary then you'll have to change your spec file. First
generate a spec file template by setting
CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE
[1]
<https://cmake.org/cmake/help/v3.6/module/CPackRPM.html#variable:CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE>
and then change it to suit your needs.

For examples you can look into CPack tests [2]
<https://github.com/Kitware/CMake/tree/master/Tests/RunCMake/CPack/tests>
(CUSTOM_BINARY_SPEC_FILE test is using a custom spec file).
