The CXX compiler identification is unknown

Question

We are having trouble compiling a project using CMake (v2.8.12) under Windows 7 64Bit using Visual Studio 2012. CMake gives us the following errors. We already tried starting Cmake from the Visual Studio Command Line using admin rights. There seems to have been a similar bug in CMake 2.8.11: http://www.cmake.org/Bug/view.php?id=14440
