Removed lib path string from OCE_DEFAULT_CSF_GraphicShr variable for MinGw
Fully removed lib path string from OCE_DEFAULT_CSF_GraphicShr variable (since it is unnecessary and potentially harmful)
Replace if(MSVC) by if(CMAKE_CONFIGURATION_TYPES OR NMAKE)

The latter is used in CMakeLists.txt to handle Debug+Release
builds.
