These instructions are a work in progress. To build the integration project:
Install Unreal Engine from source, in $HOME/UnrealEngine
Install an IDE - On Windows, install visual studio 2020 - On Linux, install visual studio code (aka 'vscode')
Git clone the integration repository in $HOME/integration
Run 'make-makefiles.py' to create all the build files and project files.
You can now launch the IDE. - In linux, the command is 'code Integration.code-workspace'
If the IDE is vscode, the IDE will tell you that some plugins are recommended. The recommendations are good: install them.
