URL: https://github.com/llvm/llvm-project/commit/f54cf61ad8e1cc6592074ddd7ad07908623ead6b DIFF: https://github.com/llvm/llvm-project/commit/f54cf61ad8e1cc6592074ddd7ad07908623ead6b.diff LOG: [OpenMP][NVPTX] Disable building NVPTX deviceRTL by default on a non-CUDA system D95466 dropped CUDA to build NVPTX deviceRTL and enabled it by default. However, the building requires some libraries that are not available on non-CUDA system by default, which could break the compilation. This patch disabled the build by default. It can be enabled with `LIBOMPTARGET_BUILD_NVPTX_BCLIB=ON`.
