Add CMake Scripts (#759)

* [skip travis] CMake: Add CMake Scripts

This add CMake scripts for the CMake build system generator.

* CUDA Support Achieved

Fastest compile via:

  cmake .. -DENABLE_CUDA=ON -DCUDA_ARCH=6.0

* CMake: openPMD & QED

* CMake: Dimension Support

WarpX_DIMS=2,3,RZ

* CCache & Out-of-Source

Enable CCache when found and prevent in-root builds (in-source okay-ish).

* CMake: CUDA C++ Language Minimum

* Add new Files

* CI: Migrate macOS to CMake

* Fortran: Enable Because Transitive

... for now :)

* CI: Migrate Linux ICC to CMake

* CI: Verbose Make

* CMake: Add Missing PSATD Sources

* CMake: PSATD, Compute, Precision, Clean
