Visual Studio QT integration
The build customizations are needed for the new Visual Studio API system. They define the options which are understood by a custom build tool.

Installation
The installation of build customizations is simple. Download the ZIP archive and extract the files to a directory. Note that you should not delete the directory afterwards, or visual studio does not find the build customizations anymore.

After you have extracted the files, you have to
Right Click on a project->select "Build Customizations"-> click on "Existing..." on the bottom left -> select the .targets file in the folder
build-customizations\msvc-10.0
Visual studio Asks you if you want to add this directory to the default search path of the build customizations. If you click yes you do not need to select the folder anymore and simply can activate the customizations in another project.

Configuration
Version 0.2: The build customizations need the environment variable QTDIR. This variable should be set to the root dir of the qt version like
C:\Qt\4.6.3
Version 0.3: The build customizations now use property sheets. You can add them throught the property manager, but you first need to open it's window.
Click on "View"->"Other Windows"->"Property Manager"
Now right click on the project within the "Property Manager" and select "Add existing Property Sheet...".
Now change into the extracted "property-sheets" folder and add at least the "qt-integration-defaults.prop" to every configuration.
