-------
|
||
|
|
|
||
|
|
Preprocessor definition values are now escaped automatically.
|
||
|
|
|
||
|
|
This policy determines whether or not CMake should generate escaped
|
||
|
|
preprocessor definition values added via add_definitions. CMake
|
||
|
|
versions 2.4 and below assumed that only trivial values would be given
|
||
|
|
for macros in add_definitions calls. It did not attempt to escape
|
||
|
|
non-trivial values such as string literals in generated build rules.
|
||
|
|
CMake versions 2.6 and above support escaping of most values, but
|
||
|
|
cannot assume the user has not added escapes already in an attempt to
|
||
|
|
work around limitations in earlier versions.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to place definition values given
|
||
|
|
to add_definitions directly in the generated build rules without
|
||
|
|
attempting to escape anything. The ``NEW`` behavior for this policy is to
|
||
|
|
generate correct escapes for all native build tools automatically.
|
||
|
|
See documentation of the ``COMPILE_DEFINITIONS`` target property for
|
||
|
|
limitations of the escaping implementation.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 2.6.0. CMake version
|
||
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior. Use
|
||
|
|
the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
