From 0e78e5080262b8fa7a86f7cd0c8716839db048f6 Mon Sep 17 00:00:00 2001 From: Oswald Buddenhagen Date: Wed, 5 Sep 2012 18:29:19 +0200 Subject: port qmake to qt creator's qmake language evaluator this is a monster commit which does the following things: - import the evaluator as-is from qt creator into qmake/library/ - integrate it into qmake's makefiles - overwrite proitems.h with actual special types - remove the parts of Option which are redundant with QMakeGlobals - make QMakeProperty a singleton owned by Option::globals. the dynamic handling so far made no sense. - make QMakeProject a subclass of QMakeEvaluator, with relatively few extensions the changes to existing qmake code outside project.* and option.* are minor. implementing the changes gradually would mean changing a lot of code which will be just replaced in the next commit, so i'm not wasting my time on it.
