Create a new port from https://github.com/NVIDIA/NVTX/releases/tag/v3.2.2.

• Help [libtorch] update to v2.8.0 #46700
• https://github.com/NVIDIA/NVTX/blob/release-v3/c/CMakeLists.txt

It's a header-only library, and the recent version supports find_package(nvtx3)

The following packages are already installed:
    nvtx3:[email protected]
Total install time: 546 us
nvtx3 provides CMake targets:

  # this is heuristically generated, and may not be correct
  find_package(nvtx3 CONFIG REQUIRED)
  target_link_libraries(main PRIVATE nvtx3::nvtx3-c nvtx3::nvtx3-cpp)

Target CUDA::nvToolsExt and CUDA::nvtx3

• https://cmake.org/cmake/help/v4.1/module/FindCUDAToolkit.html#nvtoolsext
• https://cmake.org/cmake/help/v4.1/module/FindCUDAToolkit.html#nvtx3

Some times, CUDA configuration may fail with creating nvToolsExt target.
Using the port will prevent the header search failures.

• Add cmake hints to USE_SYSTEM_NVTX for nvtx3 include dir pytorch/pytorch#147418
• https://github.com/pytorch/pytorch/blob/e2d141dbde55c2a4370fac5165b0561b6af4798b/cmake/public/cuda.cmake#L172-L187

CMake Error at cmake/public/cuda.cmake:186 (set_property):
  The link interface of target "torch::nvtoolsext" contains:

    CUDA::nvToolsExt

Checklist

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.
