c++ - CMake: The C compiler identification is unknown

Question

I am trying to build a project by cmake 2.8.12 with visual studio 10 in 32bit architecture. But I am getting these error and cmake is unable to create the project. Can anyone please suggest me a solution. Thanks.

This is the error showing in cmake-gui window:
