Title:
   QT_IMPORTS_DIR is not defined when no QML plugins are installed

Status in “cmake” package in Ubuntu:
   Fix Released
Status in “cmake” source package in Oneiric:
   Confirmed
Status in “cmake” source package in Precise:
   Fix Released

Bug description:
   When requiring the Qt4 package in a CMakeLists.txt, among the
   available variables the one called QT_IMPORTS_DIR should point to
   where QML plugins are to be installed (its value would typically be
   "/usr/lib/qt4/imports").

   However with cmake 2.8.5-1ubuntu1 in Oneiric, its value is
   "QT_IMPORTS_DIR-NOTFOUND" as evidenced when running cmake on the
   following minimal CMakeLists.txt:

       cmake_minimum_required(VERSION 2.8)
       find_package(Qt4 REQUIRED)
       message("QT_IMPORTS_DIR = " ${QT_IMPORTS_DIR})

   A quick look at /usr/share/cmake-2.8/Modules/FindQt4.cmake shows that 
the logic used to define the value of QT_IMPORTS_DIR queries qmake’s 
QT_INSTALL_IMPORTS variable.
   On the same machine, the query returns the expected value:

       $ qmake -query QT_INSTALL_IMPORTS
       /usr/lib/qt4/imports

   So the logic to define QT_IMPORTS_DIR in 
/usr/share/cmake-2.8/Modules/FindQt4.cmake is somehow faulty.
   I have tested the above both on x86 and amd64, with the same results.
