How to pass extra flags to package?

[dkaszews]

I am testing performance of my project and have noticed significant speedup with `add_cxxflags('-march=native'). Is there an easy way to pass this flag to Cmake-based packages on xrepo, for example hyperscan, or do I need to fork each of them and provide it as a new config option?
