'''NOTE:''' This buildsystem is the official buildsystem starting with openvpn 2.3-alpha2. The rest of this article is thus more or less outdated.

This new buildsystem is available in [https://github.com/alonbl/openvpn-build GitHub]. For usage documentation, take a look [wiki:BuildingUsingGenericBuildsystem here].

'''NOTE:''' Instead of merging these patches from the mailing list, the content should be pulled from Alon's updated repositories:

 * https://github.com/alonbl/easy-rsa
 * https://github.com/alonbl/openvpn-gui/tree/build
 * https://github.com/alonbl/openvpn/tree/build
  * includes some additional changes to the "msvc" build
