I've tried time and time again, I've made a build file, I've tried cmake and cmake .. but it's always saying "cmake not found". This is why I never download tar files but I absolutely need to download this one. Thank you for your help.

really helps if you tell us what distro you are using

do you have a package called cmake installed? may also need automoc4

do you any compilers and development libraries installed? your distro might have a shortcut to install a basic set of compilers and libraries need for development

what are attempting to compile? why did you post under K3b (assuming it's not K3b)
