Patch is partially made by Pelle Johnsen. Thanks!
This patch enables search for specific libraries for vc2010 using "set_lib_path" macro
If *x* library or path exists in lib/win___/vc2010/*x* , vc2010 will use it. If not, compiler will use standard libraries.
It can be easily extended to gcc.

The function is enabled for:
openCollada
openExr
Python
openImageIO

The different libraries are needed for different compilers because C++ was used. There is no standard for lib's C++ structure/functions' names.

Actual libs will follow
