The following procedure can be used to build natively on a 64-bit system or to cross-compile from a 32-bit system.
When building 64-bit binaries, the output directory will be one of the following Berkeley DB subdirectories, depending upon the configuration that you chose:
| build_windows\x64\Debug | 
| build_windows\x64\Release | 
| build_windows\x64\Debug_static | 
| build_windows\x64\Release_static |
