New Revision: 478808
URL: https://svnweb.freebsd.org/changeset/ports/478808

Log:
  graphics/py-open3d-python: Fix build failure on 12
  
  12 has the failure:
  /usr/local/bin/ld: /usr/bin/../lib/LLVMgold.so: error loading plugin: Cannot open "/usr/bin/../lib/LLVMgold.so"
  c++: error: linker command failed with exit code 1 (use -v to see invocation)
  that is triggered by the -flto argument. It isn't supplied on 11.
  
  Add patch that eliminates -flto altogether.

Added:
  head/graphics/py-open3d-python/files/patch-External_pybind11_tools_pybind11Tools.cmake   (contents, props changed)

Added: head/graphics/py-open3d-python/files/patch-External_pybind11_tools_pybind11Tools.cmake
