review non-advanced CMake variables
- CUDA_USE_STATIC_CUDA_RUNTIME -- useful or not?

In master, it could be useful to change at least some of the documentation

that could also enable messages about not finding the components needed
for the documentation build, but that is outside the scope of this
Mark more variables as advanced
