KDE is a comprehensive desktop environment with a huge number of applications written for it and a huge amount of users. It is based on the Qt framework.
There are two versions of KDE. KDE4 is a deprecated version that combines libraries and the desktop environment into one set of packages. It is no longer in BLFS. For KDE5, the libraries, now called KDE Frameworks 5 or KF5, are separate from the desktop environment called KDE Plasma 5.
