[vtkusers] installing vtk and cmake

[Ali]

Dear all 
How can I install VTK on LINUX using Cmake, I have tried to install
CMake. I have saved VTK in one directory and cmake in another. How can I
install cmake and then how can I install VTK, I have followed the
instructions on the instllation guides, but no luck. I have tared the
cmake in its directory, now how can I complete the instllation using
"ccmake" or "cmake -i" commands. Any help is appreciated.
