hi guys,
I've freshly install visual studio from unity,
and downloaded the last version of of 0.9.0
the package works properly but ofxFaceTracker basic exemple struggle to compile
this is what I get:
I can just comment the 4 first error they are not really necesary but the 2 last ones I really dont know how to solve them
It did use to work perfectly on OSX and linux 
error LNK2019: unresolved external symbol "float __cdecl
