Can't build OpenSubDiv 3.6.0 on OpenBSD

[brad0]

Trying to update from OpenSubDiv 3.5.0 to 3.6.0 it is now failing to build.

I think it might have something to do with this commit.

https://github.com/PixarAnimationStudios/OpenSubdiv/commit/05abd4e826ab19fec006df326fa5e4be40b354e8

The header path to /usr/X11R6/include is missing.

Could you attach a copy of your CMakeCache.txt?

Thanks!

Any update on this? I have a workaround for now. But CMake should be fixed.
