Absolute paths are ridiculous. All we need - and all we are allowed, by the way - is to use a folder on the same level that the folder containing .pro file for shadow builds. There are bugs otherwise.
But you can't just specify ../mingw_debug
for example. Yes, it is a relative path but relative to what? It turns out it is relative to current directory of Qt Creator, and this is completely meaningless.
%{sourceDir}
is of no help either. %{sourceDir}/../mingw_debug
dosen't work, at least on Windows. If there was a way to extract parent folder from sourceDir!
Does anybody know a way to solve the issue?
In Qt Creator 3.6.1 at least, this is fixed - relative paths work just fine. The resolved full path is shown in the tooltip. I don't know when in the past few years this was fixed.
