CUDA 12 removed cudaThreadSynchronize(); CUDA 13.x therefore fails to build:

    opensubdiv/osd/cudaEvaluator.cpp:379:5: error: 'cudaThreadSynchronize' was not
    declared in this scope; did you mean 'cudaStreamSynchronize'?

Upstream fixed this by calling cudaDeviceSynchronize() on the dev branch
(issue #1377, internal OSD-477). The call is still present in the newest
release tarball (v3_7_0), so it is patched here instead of bumping.
