Noon, As far as I see the DWG driver is compiled as a plugin so you should either place it into a /gdalplugins subdirectory from where your application is running, or set the location of this dll in the GDAL_DRIVER_PATH environment variable. Also make sure the location of the dll-s from the dependent libs are also added in PATH.
