It is somewhat template heavy (including thrust dependency) and suboptimal in that manner. Some examples are: we are specializing matrix on the vector precision and vector - on the matrix precision, which is unnecessary. It might require some heavy refactoring to improve that.
I should also mention that windows build using cmake is not optimal as well - cmake generates such projects and solution that MSVS parallelize only over projects, but not over files inside the project. So yeah, building on windows is quite an adventure :) Linux is much more modest in that manner.

As for the warnings you have mentioned - i've never seen this. Sounds like unfortunate mix of cl and cuda headers, i don't think this is AMGX specific.
