I updated QtC to version 4.12.3 (QBS 1.16.0). After that, parsing my
project from scratch took 4-7 seconds. With this times is possible to
work quite comfortably. Thanks for speeding up! :)))

It brings a ~44% speed improvement in the problematic case according to your

Thanks, Richard!
So for "medium" projects in terms of depth of the dependency tree, it's
sensible to use transitive
example:
// qbs/imports/MyBaseApplication.qbs
CppApplication {
Depends { name: "SomeLibNeededEverywhere" }
}
// in other .qbs files use MyBaseApplication instead of CppApplication
MyBaseApplication {
}

Some ideas:
1. Incremental project resolving: Take the dependency graph into account

I would like to understand why exactly this pattern

Hello.
Now I'm trying to write a QBS build script for a fairly large project
(QGIS). After making every change to the build script - the project tree
is rebuilt and QtCreator freezes for 10-15 seconds. It seems that 10-15
is not so much, but since I have to make a lot of changes in the
