[resolved] How do I debug missing find_package module (CUDAToolkit) on a specific machine?

Code

Hi,

I have a cmake project that is using find_package(CUDAToolkit).
I get this error:

-- Could NOT find CUDAToolkit (missing: CUDAToolkit_DIR)
CMake Error at cmake/find_voreen_libraries.cmake:40 (find_package):
  Could not find a package configuration file provided by "CUDAToolkit" with
  any of the following names:

    CUDAToolkitConfig.cmake
    cudatoolkit-config.cmake

  Add the installation prefix of "CUDAToolkit" to CMAKE_PREFIX_PATH or set
  "CUDAToolkit_DIR" to a directory containing one of the above files.  If
  "CUDAToolkit" provides a separate development package or SDK, be sure it
  has been installed.

To me, it seems like there’s some particularly broken about this system but I don’t know what it could be. I just installed latest stable release of cmake just in case, but I still get the same issue. The modules are there:

/usr/share/cmake-3.20/Help/module/FindCUDAToolkit.rst
/usr/share/cmake-3.20/Modules/FindCUDAToolkit.cmake

but cmake is not finding them.

What should I do next?
The find_package for cudatoolkit works elsewhere (both windows and linux), just not on that machine. So it’s definitely not a typo somewhere.

No idea what happened. Clearly there are some issues with the environment, but it works now.
