CUDA / GPU support not working on Fedora 36/37

[sigmabeta]

Howdy's set up and works great for me. However, digging around in the settings I note that there's an option to use the CNN algorithm, which is intended for use with CUDA. Enabling it does not result in GPU usage reported by nvidia-smi.

Digging around the issue tracker, I realized the issue is that dlib does not have CUDA support enabled, and that some users were able to fix this by simply using pip3 to reinstall that library.

That makes sense; however, pip3 does this by attempting to build from source. That's great, but it's failing on my machine because of missing CUDA development libraries. The key snippet from the error output:

      -- Found BLAS and LAPACK via pkg-config
      CUDA_TOOLKIT_ROOT_DIR not found or specified
      -- Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (Required is at least version "7.5")
      -- Found CUDA, but CMake was unable to find the cuBLAS libraries that should be part of every basic CUDA install. Your CUDA install is somehow broken or incomplete. Since cuBLAS is required for dlib to use CUDA we won't use CUDA.
      -- DID NOT FIND CUDA
      -- Disabling CUDA support for dlib.  DLIB WILL NOT USE CUDA

Fedora DNF on the other hand, disagrees:

Package xorg-x11-drv-nvidia-cuda-libs-3:520.56.06-1.fc37.x86_64 is already installed.
Package xorg-x11-drv-nvidia-cuda-libs-3:520.56.06-1.fc37.i686 is already installed.

If I'm misunderstanding and this package does not contain the correct files, please correct me.

Linux distribution (if applicable): Fedora 37 Howdy version: 2.6.1
