That is the correct location of our SVN repository. But there are already some scripts available to help you with this. You can checkout all the necessary files with the script
ImageMagick\Source\Checkout.cmd
You can modify the revision in the batch file. And to build all the libraries you can execute ImageMagick\Source\BuildAll.cmd
. If you want to modify that is being build then edit the file Tools\Scripts\BuildLibraries.ps1
. The .NET 2.0 builds require Visual Studio 2010.
