[CMake] CXX and CUDACXX

[Dustyn Blasig]

Hi All,

I'd like to understand the expectations with CMake 3.12+ with the following
setup.

project(foo LANGUAGES CXX CUDA)

By default, should the CUDACXX compiler be using the found compiler for CXX
for host-side compilation?

What I'm seeing is that host-side compilation for CUDA is not passing
-ccbin to NVCC or setting up the environment in a way that nvcc will use
the CXX configured compiler but rather just using the c++ it finds on PATH.

Is there a best practice for telling the CUDA language to use the CXX
settings for host-side compilation?

Thanks!
