-------
|
||
|
|
|
||
|
|
Compiler id for Apple Clang is now ``AppleClang``.
|
||
|
|
|
||
|
|
CMake 3.0 and above recognize that Apple Clang is a different compiler
|
||
|
|
than upstream Clang and that they have different version numbers.
|
||
|
|
CMake now prefers to present this to projects by setting the
|
||
|
|
:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``AppleClang`` instead
|
||
|
|
of ``Clang``. However, existing projects may assume the compiler id for
|
||
|
|
Apple Clang is just ``Clang`` as it was in CMake versions prior to 3.0.
|
||
|
|
Therefore this policy determines for Apple Clang which compiler id to
|
||
|
|
report in the :variable:`CMAKE_<LANG>_COMPILER_ID` variable after
|
||
|
|
language ``<LANG>`` is enabled by the :command:`project` or
|
||
|
|
:command:`enable_language` command. The policy must be set prior
|
||
|
|
to the invocation of either command.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to use compiler id ``Clang``. The
|
||
|
|
``NEW`` behavior for this policy is to use compiler id ``AppleClang``.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.0. Use the
|
||
|
|
:command:`cmake_policy` command to set this policy to ``OLD`` or ``NEW``
|
||
|
|
explicitly. Unlike most policies, CMake version |release| does *not* warn
|
||
|
|
by default when this policy is not set and simply uses ``OLD`` behavior.
|
||
|
|
See documentation of the
|
||
|
|
:variable:`CMAKE_POLICY_WARNING_CMP0025 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
|
||
|
|
variable to control the warning.
