Is there some way to build a package for all widgsets in one go like the IDE's Build Many option?

Changing widgetsets results in a recompile of a lot of GUI packages and wonder whether that can be avoided. Adding the LCLWidget to the output path of packages doesn't seem to work.

The only way I can think of is to have separate Lazarus builds for each widget set which share the same --pcp option. For cross-platform I mainly use Qt as the GTK widget set doesn't seem to work well on Windows.

You can use different target directories for different targets/widgetsets in Additions and Overrides.

Adding the LCLWidgetType to the output directory allows to compile for each widgetset only once. The Lazarus sources use that too.

I suppose that this depends on using building a project with the right widgetset? My thoughts where more along the line of using the Compile button on the package to compile for all the chosen widgetsets in one go.

With "chosen" I guess you mean build modes.
You can use "Run / Build many Modes ..." to compile for all the chosen widgetsets in one go.

I am thinking along the lines of compiling "a package only". The Compile settings
for packages don't have a "Run/Build Many Modes...". That only applies to Projects.
