-      "See section 'Variable types in CMake' below for details of "
-      "regular and cache variables and their interactions. "
-      "If CACHE is used, <type> and <docstring> are required. <type> is used "
-      "by the CMake GUI to choose a widget with which the user sets a value. "
-      "The value for <type> may be one of\n"

-      "If <type> is INTERNAL, the cache variable is marked as internal, "

-      "This is intended for values that should be persisted in the cache, "
-      "but which users should not normally change. INTERNAL implies FORCE."
-      "\n"
-      "Normally, set(...CACHE...) creates cache variables, but does not "
-      "modify them. "
-      "If FORCE is specified, the value of the cache variable is set, even "
-      "if the variable is already in the cache. This should normally be "
-      "avoided, as it will remove any changes to the cache variable's value "

-      "If PARENT_SCOPE is present, the variable will be set in the scope "
-      "above the current scope. Each new directory or function creates a new "
-      "scope. This command will set the value of a variable into the parent "
-      "directory or calling function (whichever is applicable to the case at "
-      "hand). PARENT_SCOPE cannot be combined with CACHE.\n"
-      "If <value> is not specified then the variable is removed "
-      "instead of set.  See also: the unset() command.\n"
-      "  set(<variable> <value1> ... <valueN>)\n"
-      "In this case <variable> is set to a semicolon separated list of "
-      "values.\n"
-      "<variable> can be an environment variable such as:\n"
-      "  set( ENV{PATH} /home/martink )\n"
-      "in which case the environment variable will be set.\n"
-      "*** Variable types in CMake ***\n"
-      "In CMake there are two types of variables: normal variables and cache "
-      "variables. Normal variables are meant for the internal use of the "
-      "script (just like variables in most programming languages); they are "
-      "not persisted across CMake runs. "
-      "Cache variables (unless set with INTERNAL) are mostly intended for "
-      "configuration settings where the first CMake run determines a "
-      "suitable default value, which the user can then override, by editing "
-      "the cache with tools such as ccmake or cmake-gui. "
-      "Cache variables are stored in the CMake cache file, and "
-      "are persisted across CMake runs. \n"
-      "Both types can exist at the same time with the same name "
-      "but different values. "
-      "When ${FOO} is evaluated, CMake first looks for "
-      "a normal variable 'FOO' in scope and uses it if set. "
-      "If and only if no normal variable exists then it falls back to the "
-      "cache variable 'FOO'.\n"
-      "Some examples:\n"
-      "The code 'set(FOO \"x\")' sets the normal variable 'FOO'. It does not "
-      "touch the cache, but it will hide any existing cache value 'FOO'.\n"
-      "The code 'set(FOO \"x\" CACHE ...)' checks for 'FOO' in the cache, "
-      "ignoring any normal variable of the same name. If 'FOO' is in the "
-      "cache then nothing happens to either the normal variable or the cache "
-      "variable. If 'FOO' is not in the cache, then it is added to the "
-      "cache.\n"
-      "Finally, whenever a cache variable is added or modified by a command, "
-      "CMake also *removes* the normal variable of the same name from the "
-      "current scope so that an immediately following evaluation of "
-      "it will expose the newly cached value.\n"
-      "Normally projects should avoid using normal and cache variables of "
-      "the same name, as this interaction can be hard to follow. "
-      "However, in some situations it can be useful. "
-      "One example (used by some projects):"
-      "\n"
-      "A project has a subproject in its source tree. The child project has "
-      "its own CMakeLists.txt, which is included from the parent "
-      "CMakeLists.txt using add_subdirectory(). "
-      "Now, if the parent and the child project provide the same option "
-      "(for example a compiler option), the parent gets the first chance "
-      "to add a user-editable option to the cache. "
-      "Normally, the child would then use the same value "
-      "that the parent uses. "
-      "However, it may be necessary to hard-code the value for the child "
-      "project's option while still allowing the user to edit the value used "
-      "by the parent project. The parent project can achieve this simply by "
-      "setting a normal variable with the same name as the option in a scope "
-      "sufficient to hide the option's cache variable from the child "
-      "completely. The parent has already set the cache variable,  so the "
-      "child's set(...CACHE...) will do nothing, and evaluating the option "
-      "variable will use the value from the normal variable, which hides the "
-      "cache variable.";
