trying to compile llvm 11 from source with cmake 3.19, former pulling in Google’s benchmarking https://github.com/google/benchmark/blob/master/CMakeLists.txt#L263 which tests for
- GNU_POSIX_REGEX
- POSIX_REGEX
and the test fails as apparently neither is available on the node.
since the node is based on the Debian package feed I was trying to find a package that satisfies either one but came up empty.
