Should note that this issue occurred with and without a remote cache.

test_main.cc is listed as a source in each one of the test targets, so it's compiled each time. Put the test support code in its own cc_library to avoid that.

Indeed it is: https://github.com/ryanhaining/cppitertools/blob/master/test/make_tests.bzl#L5

Closing this.
