[CMake] issue with searching dll

I got an issue when trying to generate our VS2010 project with CMAKE, it report an error on existence of qt modules dlls.

The macro "_populate_Qml_target_properties" check the existence of dlls in the lib directory instead of the bin one.

It affect all Qt modules

For exemple in the file :
C:\Qt\SDK-5\5.1.0-rc1\msvc2010_opengl\lib\cmake\Qt5Qml\Qt5QmlConfig.cmake

We replaced line 31
set(imported_location "${_qt5Qml_install_prefix}/lib /${LIB_LOCATION}")
by this one
set(imported_location "${_qt5Qml_install_prefix}/bin /${LIB_LOCATION}")
to fix the issue.

Please notice that I didn't check if it's also the case with mingw configuration or on others platforms.
