cmake: say 'absolute path' in option descriptions and docs

Browse Source 
To not have to guess. Also to sync with autotools, which already uses
this wording.

Also:
- replace the stray term 'folder' with 'directory' for consistency.
- store help text in a temp variable to avoid overly long strings
  (mandatory in CMake <4.2.0 and can't be trivially split), also
  to avoid repeating this string 4 times.

Ref: https://cmake.org/cmake/help/v4.2/command/set.html
