Is your feature request related to a problem? Please describe.

@cliffburdick requested that we build MatX in our CI, similar to what we do for RAPIDS.

Describe the solution you'd like

Build-only checks are sufficient. This can be done via:

git clone [email protected]:NVIDIA/MatX.git
cd MatX
mkdir build
cd build
cmake -G Ninja .. -DMATX_BUILD_TESTS=ON -DMATX_BUILD_EXAMPLES=ON -DMATX_BUILD_BENCHMARKS=ON -DMATX_EN_CUTENSOR=ON
cmake --build

Describe alternatives you've considered

No response

Additional context

MatX depends on features that we do not provide in our default devcontainers. We'll need to make a dedicated devcontainer for MatX.

Our devcontainer infra repo's yaml file disables installCTKLibraries and installcuTensor for CCCL. We should be able to just define a new config with those enabled.
