I have a large solution (163 projects) which I want to convert to the new Qt/MSBuild system.

When I right click on the solution in the solution explorer and select 'Convert custom build steps to Qt/MSBuild', I'm alway getting an error:

'Warning: No projects to convert.'

When selecting multiple projects in the solution explorer, there is no context menu option to convert the projects.

When selection the solution (or even a single project) in the solution explorer and selecting 'Qt VS Tools->'Convert custom build steps to Qt/MSBuild' from the main menu, I'm always getting the error:

'Warning: No projects to convert.'

So I cannot find any option to quickly convert my solution right now, I have to manually convert every single project.
