Subject: [PATCH] Fix FindOpenMesh.cmake

```
CMake Error at C:/CGAL/test/CGAL-5.1-Ic-33/cmake/modules/FindOpenMesh.cmake:54 (set_target_properties):
  Property INTERFACE_LINK_LIBRARIES may not contain link-type keyword
  "optimized".  The INTERFACE_LINK_LIBRARIES property may contain
  configuration-sensitive generator-expressions which may be used to specify
  per-configuration rules.
