Problem Compiling with Ming on Windows

Trying to build on Windows with libevent 1.4.12 to see if I can get Sockets to work. Cmake finds the correct directories for libevent, yajl, and readline. When I try to compile I get this error:

-------------------------
Linking C shared library _build\dll\libIoRandom.dll
Creating library file: _build\dll\libIoRandom.dll.a
CMakeFiles\IoRandom.dir/objects.a(IoRandom.c.obj): In function `IoRandom_proto':

C:/src/io/addons/Random/source/IoRandom.c:76: undefined reference to `IoState_registerProtoWithFunc_'

mingw32-make[2]: *** [addons/Random/_build/dll/libIoRandom.dll] Error 1
mingw32-make[1]: *** [addons/Random/CMakeFiles/IoRandom.dir/all] Error 2
mingw32-make: *** [all] Error 2

Any pointers?

Thanks,
