My question is, if there is a way to declare a variable in a PRO file, so it is visible in all subproject?
I have a project that has different build options, where different flags to the compiler are passed. I want to have a base PRO file for each of the different builds and in these PRO files to define the different flags.
The horrible alternative is to create different versions of every subproject.
I am also aware that I can pass to QMake a variable that defines which build to execute, but in Qt Creator those are kept in the .user file, which is not under version control and is not share amongst developers.
