Building the Viewer with Autobuild
If you haven't done so already, install autoubuild. Full instructions can be found on the Autobuild page, but most users may simply use
pip install autobuild
Build a desired configuration
With a properly configured developer machine (see ...), building the viewer with autobuild is as simple as invoking
autobuild build -c [CONFIGURATION]
where CONFIGURATION stands for the build configuration you would like to build.
