Is this a duplicate?

Area

cuda.pathfinder

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

Add support for find_nvidia_header_directory for:

  • mathdx
    • cufftdx
    • cublasdx
    • cusolverdx
  • cutlass

Describe the solution you'd like

find_nvidia_header_directory("mathdx") returns header path of installed mathdx (either through pypi, conda or tarball):

Describe alternatives you've considered

I'm currently search for libraries manually

Additional context

Needed for nvmath

    I'm revamping the prioritization for all pathfinder issues.

    Hi @ZzEeKkAa I'm finally getting to this. I believe PR #1816 should already work for PyPI and Conda.

    Could you please help me understand:

    1. How are the tarballs usually installed (target directory)?

    2. Why is there no libmathdx\.h?

    $ tar ztvf nvidia-mathdx-25.12.1-cuda13.tar.gz | grep -e 'libmathdx\.h' -e 'cutlass/cutlass\.h' -e 'cute/tensor\.hpp'
