Subject: [PATCH 2/3] Refactor CMakeLists.txt for mingw cross-compile

Two things:
1) By default, Linux CMake puts -fPIC on the link line. So we remove that
for MINGW to avoid warnings that it will be ignored.
2) Similarly, move -fvisibility=hidden flag to be for non-mingw
compilation only to avoid warnings that it will be ignored.
