The workaround cdd4f06 (from #476) broke MSVC building (reported in #489). I didn't test MSVC in #476. MSVC refuses to resolve the symbol because the return type is different, which was the point of the workaround.
Alternative workarounds would make it more a mess. I have sent a patch to iai_kinect2 directly to use new API. code-iai/iai_kinect2#189
Build tested OK with MSVC and GCC after this PR.
