Your task

CMake is our build structure: inside every CMakeLists.txt you can find a list of files to be compiled and a given set of options. Very powerful, opensource and crossplatform, visit www.cmake.org to read documentation.

This task involves writing one line description to every important variable used in all our CMakeLists.txt. Basically every variable must be updated from set(VAR ${VALUE}) to set(VAR ${VALUE} CACHE STRING "DESCRIPTION").

Deliverable

A working patch, that applies cleanly to our source tree. This patch should be in the form of a pull from clone, hg export or unified diff format (in order of preference) implementing the functionality required.
