All CMake tools command line do have some builtin documentation support. The tools (cmake, cpack, ctest) supports a variable subset of:

  ctool --help-command[-list]
  ctool --help-module[-list]
  ctool --help-variable[-list]
  ctool --help-policy[-list]
  ctool --help-property[-list]
  ctool --help-full
  ctool --help-html
 
for the detail see:
 
  cmake --help
  cpack --help
  ctest --help
 
This builtin documentation comes from 2 different places:
# static variables in C++ sources
# text surrounded by markup in CMake script files
 
== Documentation in C++ sources ==
 
This is the primary source of builtin documentation.
 
== Documentation markup in CMake script files ==
 
This source is available since CMake 2.8.8 and is currently only used by CPack.
The idea behind CMake script markup is to be able to document CMake scripts. Documenting a script means being able to put in structured documentation using some comments.
 
Before 2.8.8, this was available through:
cmake --help-module
which was basically extracting the first block of comments stripping out the comment character ('#').
 
From 2.8.8 and up we may be able to do more by using a basic markup language which may be used to document
- variable
- command
- section
 
The markup may then be automatically extracted by ctool (cmake, cpack, ctest) in order to feed their
  --help-variable[s|-list]
  --help-command[s|-list]
command lines options
