The OpenMP cmake module can't be found for non x64 arches (armh, aarch64, and ppc64le). This is expressed in the fact that with including "libgomp-devel", and use: find_package(OpenMP REQUIRED) raises exception "Could NOT find OpenMP_CXX": [armh] CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message): [armh] Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES) [armh] Call Stack (most recent call first): https://git.altlinux.org/tasks/255607/logs/events.56.1.log Can be reproduced by rebuild the libkgraph package without ExcludeArch keyword in spec.
