This PR adds a
RE2_BUILD_NO_BENCHMARKS
CMake option, which (in combination withRE2_BUILD_TESTING
) makes it possible to build and run tests without also building and running benchmarks. The default behavior is unchanged in both theRE2_BUILD_TESTING=OFF
andRE2_BUILD_TESTING=ON
cases.This can be useful for people like Linux distribution packagers, who do want to run tests but do not necessarily care about benchmarks, and who might prefer to avoid the dependency on https://github.com/google/benchmark. (I maintain
re2
in Fedora.)
