Well Qt is one of my external dependencies and thus is stored in a
intern vcs repository. It is then used by a continuous integration
build system that updates and build the code. This CI cannot write
outside of the checked out code directory and it is (much) faster to
remove one directory to clean a build than to delete everything and
recheckout the code.

a first step was to change one condition in bin/syncqt

--- a/bin/syncqt
+++ b/bin/syncqt
@@ -333,7 +333,7 @@ sub syncHeader {
 ######################################################################
 sub fixPaths {
     my ($file, $dir) = @_;
-    $dir =~ s=^$basedir/=$out_basedir/= if(!($basedir eq $out_basedir));
+    $dir =~ s=^$basedir/=$out_basedir/= if(!( index($out_basedir,
$basedir) eq 0));
     $file =~ s=\\=/=g;
     $file =~ s/\+/\\+/g;
     $dir =~ s=\\=/=g;

but now, qmake seems to have the same problem, it does'nt include the
correct path for the moc'ed objects :

-I/home/marache/Projects/qt4/src/corelib/.moc/release-shared
instead of
-I/home/marache/Projects/qt4/build/src/corelib/.moc/release-shared

Maybe I'm hitting a bigger wall than I first thought :-)
