The solution is not to specify this variable. Visual Studio is a multi-configuration generator. You can have all your configurations in one build tree.

Due to complexity of Slicer’s build system, we recommend to create a separate build tree for each configuration (we do not test if building with different configurations in the same build tree works or not, so probably it does not work). This means that after you build Slicer in Debug mode, you need to create a new build tree if you want to build in release mode as well.
