Hi,

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

```auto
-- 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:

```auto
/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.

Eric

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