           Summary: [Qt] WebKit fails to detect QtQuick2 if Qt is built
                    with -prefix
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: hausmann at webkit.org
                CC: vestbo at webkit.org


In a top-level Qt build, a .qmake.super file provides QMAKEMODULES += /path/to/modules/mkspecs lines that allow qmake to locate other Qt modules prior to their installation to the target prefix, allowing for example WebKit to link compile and link against QtQuick2.

When build-webkit calls qmake on configure.pro to detect modules and system features, qmake is invoked with -nocache, which disables the reading of the .qmake.super file and therefore results in WebKit failing to detect the presense of QtQuick2 and other modules.


One possible solution would be to manually remove the .qmake.cache file that the -nocache parameter tries to circumvent prior to calling qmake on configure.pro, another solution would be to get rid of this step altogether and always use configure.pro from within the top-level WebKit.pro.
