Earlier feedback for syntax errors in shaders

This turned out to be a small error inside a CMake script which slipped into the OptiX SDK 7.5.0 release but can easily be resolved locally.
It’s going to be fixed in the upcoming OptiX SDK release.

Inside CMake/cuda/FindCUDA/run_nvcc.cmake you replace these two lines:

function(cuda_execute_process status command) 
...
endfunction()

with

macro(cuda_execute_process status command)
...
endmacro()
