CUDA 11 support?

just asking..

This appears to be due to the expected change in NVRTC no longer having /usr/include on the header search path.

In previous CUDA toolkits, NVRTC on Linux incorrectly added "/usr/include" to the default header file search path. This issue has been fixed; NVRTC in CUDA 11.0 and later will not implicitly add '/usr/include' to the header file search path.

If some included files are present inside /usr/include, the NVRTC nvrtcCompileProgram() API call must now be explicitly passed the "/usr/include" path with the "-I" flag.

The jitify compiler error we see is:

stdlib.h(3): catastrophic error: could not open source file "stddef.h" (no directories in search list)

I think this is actually a different issue, and it should have been fixed with 40df041. Do you have that commit?

Our jitify version seemed to be a little out of date, now I've updated it CUDA 11 is working fine for our (flamegpu) use.
