[MPlayer-cygwin] How to compile MPlayer for WIN32 using MinGW

[Eugene Kovgar]

Hello. I have problems configuring schroedinger-1.0.6. During configuring 
follows next error:

checking for pkg-config... /home/Eugene/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for LIBOIL... The system cannot find the path specified.
no
configure: error: liboil-0.3 >= 0.3.16 is required


The thing is my liboil package version is really 0.3.16 and was compiled well. 
What should I do? Thanks.
