Summary:                    fixup_qt4_executable fails on Linux when used with
CPack or DESTDIR
Description: 
When CPack is used on a build where cmake has been run to set up the packaging,
the fixup_qt4_executable() functon (defined in the DeployQt4 module) complains
that it cannot find the executable. This only occurs on Linux. The same files
work as expected on Windows (I don't have access to Mac to test on there,
sorry).

What is interesting is that if I look at the cmake_install.cmake file that is
generated by CMake, both contain a line like one of the following:

FIXUP_QT4_EXECUTABLE("${CMAKE_INSTALL_PREFIX}/bin/myExe" "" ""
"/usr/lib64;/usr/lib64/qt4/bin" "" "")

FIXUP_QT4_EXECUTABLE("${CMAKE_INSTALL_PREFIX}/bin/myExe.exe" "" ""
"C:/QtSDK/Desktop/Qt/4.8.1/msvc2008/lib;C:/QtSDK/Desktop/Qt/4.8.1/msvc2008/bin"
"" "")

If I run CPack on these, it works fine on Windows, but on Linux it complains
that it cannot find the executable. It is as though the DESTDIR used by CPack to
get "make install" to install to a private area is not understood by
fixup_qt4_executable(). Why it works on Windows but not on Linux is unclear. I
also confirm that simply doing a "make DESTDIR=somewhere install" also fails in
a similar fashion, so it is not a problem with CPack.

Steps to Reproduce: 
See the simple example (I'll attach the files shortly). On linux, run cmake and
then do a make install with DESTDIR set to somewhere.
