 From commit e827cb144ee9886134a946c7a3b316f9eeb83168 ("qtcreator: 
Create *.pro.shared files instead of *.pro.user") on, *.pro.shared files 
will be generated.
If you still don't want to use the autogenerated and autoselected kit 
with build/run settings, this will at least make sure you don't have to 
configure your custom settings every time, since the *.pro.user file 
holding the settings is no longer overwritten every time that
'make qtcreator-ide-integration' is run.

I've seen a similar error message to yours when testing with a separate 
build dir that is not on the same "hierarchy level" in the file system 
as the source dir (srcdir: ~/development/git/libreoffice, builddir: 
~/temp/lobuild):

     ~/development/git/libreoffice/lo.pro:-1: error: Could not find .pro 
file for subdirectory "../../development/git/libreoffice/UnoControls" in 
"~/development/git/libreoffice/../../development/git/libreoffice/UnoControls".

Pending Gerrit change [1] ("qtcreator: Create *.pro and *.pro.shared 
files in builddir, not srcdir") (and its ancestors) should fix cases 
where builddir != srcdir, hopefully fixing your problem as well (for 
which I don't know the details, so can't explicitly test that).

I'll update the wiki entry [2] later, once everything has been merged.
