81 strings throughout evaluation. Wrapping a variable in ``${}`` dereferences it
83 this as "variable evaluation" in their documentation. Dereferences are performed

97 Dereferencing an unset variable results in an empty expansion. It is a common
99 code paths that the variable isn't set. There are examples of this throughout
102 An example of variable empty expansion is:
104 .. code-block:: cmake
111 In this example the ``extra_sources`` variable is only defined if you're
115 One big "Gotcha" with variable dereferencing is that ``if`` commands implicitly

131 This works because while ``MSVC`` is a defined variable, ``xMSVC`` is not. This

189 flags options, which CMake refers to using the following variable expansions:
196 associated with them. The variable's type is used by CMake's UI tool to display
197 the right input field. The variable's type generally doesn't impact evaluation.

206 CMake inherently has a directory-based scoping. Setting a variable in a
207 CMakeLists file, will set the variable for that file, and all subdirectories.
211 When a variable that is already set is set again in a subdirectory it overrides
215 variable into the parent scope, and not the current scope. The CACHE option sets
216 the variable in the CMakeCache, which results in it being set in all scopes. The
217 CACHE option will not set a variable that already exists in the CACHE unless the
