cci supports dll compilation on windows.

CCI should support dll compilation on windows. For now even i set cmake parameter BUILD_SHARED_LIBS on command line, there are several issues.

1. top CMakeLists.txt line 228, there is a syntax error in set (BUILD_SHARED_LIBS OFF CACHE BOOL "Build shared libraries." FORCE)
2. if comment out the line 226-228, there are still unresolved symbol error during linking/build time, suggest to add following
   set_target_properties(cci PROPERTIES
   WINDOWS_EXPORT_ALL_SYMBOLS TRUE
   POSITION_INDEPENDENT_CODE ON
   )
