Right now, the Blender trunk doesn't compile out-of-the box with OpenCollada
enabled using cmake, because
1) OPTION(WITH_OPENCOLLADA "Enable OpenCollada Support (
(that is easily fixed, and I assume it is because things are still
2) the include path and library path are not correctly set
It would be good that if OPENCOLLADA is not defined, it should use
lib/<platform> from the Blender SVN repository.
For example OPENCOLLADA should point to lib/<platform>/opencollada/include
Library include path is set to \usr\local\opencollada for Windows, it should
3) why does one platform (Mac/Apple) use OPENCOLLADA_INC and all the others
I haven't had time for a patch yet, but is someone (Arystan or someone
else) looking into this?
