**Describe the bug**



In my CMake project, I depend on Abseil, but have `BUILD_TESTING` disabled, so Abseil tests are not built.



I have my own tests. In my tests I use GoogleTest/GoogleMock and Abseil.  In particular, one of my tests depends on `absl::random_mocking_bit_gen` target.  This target is a TESTONLY library that is meant to be used by any tests, including mine.



But as I keep `BUILD_TESTING` disabled, TESTONLY libraries are not build and I'm unable to depend on Abseil test support code in my tests.



Looks like building test support libraries should be separated from building full-fledged tests.



**What build system are you using?**
