I am trying to use a custom build system with a project. I know I can setup custom build systems through project files, but what I want to do is to select and EXISTING custom build system from within a project file. I really don’t want to duplicate the build system settings within each project file.

I have tried adding the line

"build_system": "Packages/User/myBuild.sublime-build",

to my project file, but the selected build system remains on “Automatic” when the project is loaded. I can manually choose the build system and it is stored in the workspace, but I have my ST project files being automatically generated for new projects and want to pick my custom build at the same time.

Any advice?
