> Let me check how to use %set_build_flags with CC=clang CXX=clang++. Maybe my intent using the cmake options -DCMAKE_C_FLAGS -DCMAKE_CXX_FLAGS was I wanted to align with the usage in the upstream [1]. I have a resistance to use %set_build_flags in this case, as it has the exported environment variables [2] with the wider scope in %check where I want to run 4 test cases changing the environment variables for each test case. Though I still do not know how to use %set_build_flags for clang, I can go ahead with the current spec file.
