It’s been a few years since I used CMake/CPack to generate RPMs, but the requirement arose recently, so I grabbed the packaging section from a previous project and voila I had an RPM.
However, when I examine the RPM with rpm -qlp my.rpm I see these files in /usr/lib/.build-id that I’ve never seen before. Doing a little digging, I see that rpmbuild can control the generation of these files with the %_build_id_links variable.
What I don’t know is if it is good to suppress this information in my RPM, and if so, how to do it using CMake/CPack variables or other native means, rather than writing my own spec file.
That’s the way to go. CPackRPM is using rpmbuild command in order to create RPMs.
The default behavior of rpmbuild may depends on system specific RPM macros: https://rpm-packaging-guide.github.io/#rpm-distribution-macros
which are not under CPackRPM control.
(re)defining your appropriate value may help as you see.
