- By default, all the 3rd party dependencies are enabled.
- A dependency can be turned off by adding the "-DWITHOUT_xxx=ON" to
  the call of vcbuild.bat
- List of 3rd party dependencies and associated option to turn them off:
  - LMDB: WITHOUT_LMDB
  - LUA: WITHOUT_LUA
  - LibXML2: WITHOUT_LIBXML2
  - MaxMind: WITHOUT_MAXMIND
  - cURL: WITHOUT_CURL
