cmake FindCUDAToolkit - failed

[mdppdm]

I installed SUSAN on an Ubuntu 20.04 workstation running CUDA 11.4. During cmake, I got the following error:
########################################
CMake Warning at CMakeLists.txt:27 (find_package):
By not providing "FindCUDAToolkit.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"CUDAToolkit", but CMake did not find one.

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.

CMake Error at CMakeLists.txt:43 (message):
SUSAN does not support your CUDA toolkit version.

-- Configuring incomplete, errors occurred!

I solved this by specifying the cuda path in CMakeLists.txt and removing the rest of the Configure CUDA section

set(CMAKE_PREFIX_PATH /usr/local/cuda)
