I don't understand.
If you set RUN_TESTS and BUILD_DOCS on the same build,
how is it adding build time?
I'm just suggesting to make explicit that tests and docs

I'm just sad that we cannot reuse an existing build in another way.
But I guess the infrastructure cache (ccache or other) will be enough.
