Thanks, I tried using nmake generator i.e. - cmake ../ -G "NMake Makefiles"-  but it does not work in cmake 2.8. It fails to find the compiler. However the command - cmake ../ -G "Visual Studio 9 2008" - works fine. The errors I get are as:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown

  It fails with the following output:

I will try once I get nmake generation to work.
