Not necessarily via virtualenv, either by installing the lit pypi package or using a distro package: https://admin.fedoraproject.org/pkgdb/package/rpms/python-lit/

I don't really have a plan for gtest, but this already doesn't work for out of tree builds (unless you have the source tree on your system, but I don't think we should be relying on this).

These could come from a build tree or could be installed on this system.
