  # The REGEX feature test fails when gbench's cmake is run under CPM w/ gcc5.4 because it doesn't assume C++11
  # Additionally, attempting to set the CMAKE_CXX_VERSION here doesn't propogate to the feature test build
  # Therefore, we just disable the feature test and assume platforms we care about have a regex impl available
