Linker Errors when Building on Win64 - Problem with yaml-cpp and OIIO
Hello, i am experiencing issues when building OCIO on several windows machines and several build configs. I tried building from scratch, with vcpkg and also as part of the OpenRV build script, which uses OCIO as an dependency.
The usual error message tells of a Linker missmatch connected to yaml-cpp. I have little to no experience with CMAKE, but at least some of the errors seem to point towards multiple instances of the yaml-cpp lib being linked.
The main culprit could be oiio, since I have not been able to build any OIIO version >= 2.1. If I should move this issue to that repo, please tell.
Thanks for any help.
