Summary:                    FIND_PATH not following HINTS Command
Description: 
Hi All,

I was trying to build the VisIt software package on my Mac OSX 1.5 . This
package uses Qt 4.6.1 during its build. I ran into an issue where the QtCore
path finds my globally installed version of Qt (4.7) as apposed to the Qt
(4.6.1) installed by VisIt. 

While digging around I found that FIND_PATH (code included below) in
FindQt4.cmake is pulling information from the system path and assigning this
value to the QT_QTCORE_INCLUDE_DIR. This is causing a build failure where the
rest of the QT headers are using 4.6.1 and QtCore is using version 4.7. 

The value in ${qt_headers} points to the correct 4.6.1 location yet FIND_PATH
does not use this parameter. Adding NO_CMAKE_SYSTEM_PATH finds the proper path. 

I believe this might indicate a bug in FIND_PATH because according to the CMAKE
documentation on FIND_PATH
(http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:find_path) the
HINTS option is number three in the search order and the system path is number
five.

     _qt4_query_qmake(QT_INSTALL_HEADERS qt_headers)
     SET(QT_QTCORE_INCLUDE_DIR NOTFOUND)
     FIND_PATH(QT_QTCORE_INCLUDE_DIR QtCore
               HINTS ${qt_headers}
               ${QT_LIBRARY_DIR}/QtCore.framework/Headers
               PATH_SUFFIXES QtCore
       )

Steps to Reproduce: 
Will try to make a simpler test to reproduce this error.
