Shared variables in multi qmake directory

I have multiple qmake.pro files that are called from the root .pro file with a subdirs template.

What is the best way to change the settings for the whole build system (eg release for debugging).

Currently I can only do this by modifying each sub.pro file or using an external script to modify each .pro file.

I was hoping there was a way to share qmake variables between the sub.ir file and others.

a source to share

The only way I know to do this is to include the include file: define all your variables in the vars.pri file at the root of your project, and use include () on the .pro files to access the shared variable.

Qt Creator takes care of the problem very well. When you compile a subdir project with configuration, all child projects are compiled using config.



And there is one shadow build directory for the whole project tree.
