[Cmake] compile Hello example of CMake

[Lijun Ding]

Hello, there,

I installed pre-compiled binaries of CMake (Solaris) and
run Hello example by typing
> ccmake

Then appear:
CMake Error: error can not open file
/mnt/data/ljding/example/CMakeExample/Hello/CMakeSystemConfig.cmake

I guess I should setup some environment variables or something else,
but I checked documents of cmake, and couldn't find help.

Could someone give me advice? Thanks a lot.
