Patch issue: cuda_gl_interop.h is read-only; trying to patch anyway

[MrOCW]

Hi @jetsonhacks , I am trying to use this repo to build OpenCV in a docker build. However, I am getting this in the command line

File cuda_gl_interop.h is read-only; trying to patch anyway
patch: **** Can't create temporary file ./cuda_gl_interop.h.oaK9TUB : Read-only file system

The cmake then carries on but during the build process, there are several GL errors along the way which i think might be related to the patch issue above. Seeking your assistance.

Thanks!
