.. versionadded:: 3.22
|
|
|
|
:command:`cmake_dependent_option` supports full :ref:`Condition Syntax`.
|
|
|
|
The ``<condition>`` parameter accepts a :ref:`semicolon-separated list <CMake
|
|
Language Lists>` of conditions. CMake 3.21 and lower evaluates each
|
|
``condition`` as ``if(${condition})``, which does not properly handle
|
|
conditions with nested paren groups. CMake 3.22 and above instead prefer
|
|
to evaluate each ``condition`` as ``if(<condition>)``, where ``<condition>``
|
|
is re-parsed as if literally written in a call to :command:`if`. This
|
|
allows expressions like::
|
|
|
|
"A AND (B OR C)"
|
|
|
|
but requires expressions like::
|
|
|
|
"FOO MATCHES (UPPER|lower)"
|
|
|
|
to be re-written as::
|
|
|
|
"FOO MATCHES \"(UPPER|lower)\""
|
|
|
|
Policy ``CMP0127`` provides compatibility for projects that have not
|
|
been updated to expect the new behavior.
