Building fails on latest git master

[evertvorster]

Hi there!

Building from sources currently fails on my system. I can provide the full logs if requested, but for brevity's sake, here is the error:

--   Found lilv-0, version 0.24.26
CMake Error at /usr/lib/cmake/opencv4/OpenCVConfig.cmake:86 (find_package):
  By not providing "FindCUDA.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CUDA", but
  CMake did not find one.

  Could not find a package configuration file provided by "CUDA" (requested
  version 12.8) with any of the following names:

    CUDAConfig.cmake
    cuda-config.cmake

  Add the installation prefix of "CUDA" to CMAKE_PREFIX_PATH or set
  "CUDA_DIR" to a directory containing one of the above files.  If "CUDA"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  /usr/lib/cmake/opencv4/OpenCVConfig.cmake:108 (find_host_package)
  CMakeLists.txt:284 (find_package)

It looks like the compiler is looking for cuda 12.8 specifically.
On my system I have cuda 12.8.1 installed:

extra/cuda 12.8.1-1 (2.5 GiB 6.5 GiB) (Installed)

I also see references to opencv4. I have opencv4 installed, with cuda bindings:

extra/opencv-cuda 4.11.0-7 (79.9 MiB 1.7 GiB) (Installed)

Compilation from sources worked until fairly recently, but since it gets updated regularly and it is a rolling release something might have changed on my system that prevents building now.

Did some compiler switch related to this change recently? Which direction should I look into to solve this issue?
What are some things that I can try?

Here is some more information on my system:
