Title: Fix gd flat namespace issue, Use cmake for head

GD configure script select linker option by using MACOSX_DEPLOYMENT_TARGET, so missing MACOSX_DEPLOYMENT_TARGET causes "dyld: lazy symbol binding failed: Symbol not found: _overflow2" or similar error while using libgd.2.dyld.

Also GD head doesn't have configure script and require using cmake to make binary.
