I am a complete newbie

Well I started at the very beggining
http://bulletphysics.org/mediawiki-1.5. ... om_scratch
Downloaded Cmake and followed the instruction above(i.e. link)
But when I try to build Bullet files it says:
Check for working C compiler using: Visual Studio 10 -- broken
The C compiler "cl" is not able to compile a simple test program.
which is really odd because my Visual Studio 2010 is working nice

Can anyone explain me what is the problem? And how to solve it?
