Wwise is portable.
You can copy the entire Wwise installation directory to your source control, and sync it to your build machine.
However, you need to make sure you install the requirements listed here (PDF reader and Quicktime are optional):https://www.audiokinetic.com/library/edge/?source=InstallGuide&id=wwise_system_requirementsThe most important note is:
It is not uncommon for a crash to occur due to one or multiple missing dependencies when installing Wwise without the Launcher. The dependencies required are the following: Microsoft .NET Framework, Microsoft DirectX, and Microsoft Visual Studio Redistributable. Installing the Authoring tool through the Launcher is less troublesome because you don't have to worry about the dependencies since they are automatically provided.
