Are there any newlines in the value you're setting for the OCL
environment variable? If you copied it from my e-mail, there might be
some because of line-wrapping, but it should fit on one line. If you
set it correctly, file.exists(Sys.getenv('OCL')) should return TRUE.

Actually, I'm wrong about this. Your path contains spaces, which means
that it needs to be quoted. Otherwise the compiler will see five
separate arguments "-IC:/Program" "Files/NVIDIA"
"GPU" "Computing"
"Toolkit/CUDA/v11.7/include" instead of one and won't understand
what's
needed from it.

Does it work if you use the following call to set the environment
variable in quotes? The file.exists() test will fail, but other parts
of the package build system should work with it.

Sys.setenv(OCL = '"C:/Program Files/NVIDIA GPU Computing
Toolkit/CUDA/v11.7"')
