I guess this _USE_MATH_DEFINES is a winapi specific feature, therefore I 
feel your previous fix was more portable (see playercommon.h).

Well, I tried to write my own opencv.pc file for downloaded OpenCV 
binaries (library with installer), I couldn't figure out how to manage 
with different path notations in two worlds (Windows vs pkgconfig taken 
directly from Unix). Also I had some link-time issues, I don't remember 
now.

Can you put your complete patch on a patch tracker for Player project?
