CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT
|
|
|
|
|
--------------------------------------
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 3.14
|
|
|
|
|
|
|
|
|
|
Identification string of the compiler frontend variant.
|
|
|
|
|
|
|
|
|
|
Some compilers have multiple, different frontends for accepting command
|
|
|
|
|
line options. (For example ``Clang`` originally only had a frontend
|
|
|
|
|
compatible with the ``GNU`` compiler but since its port to Windows
|
|
|
|
|
(``Clang-Cl``) it now also supports a frontend compatible with ``MSVC``.)
|
|
|
|
|
When CMake detects such a compiler it sets this
|
|
|
|
|
variable to what would have been the :variable:`CMAKE_<LANG>_COMPILER_ID` for
|
|
|
|
|
the compiler whose frontend it resembles.
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
In other words, this variable describes what command line options
|
|
|
|
|
and language extensions the compiler frontend expects.

.. versionchanged:: 3.26
|
|
|
|
|
This variable is set for ``GNU``, ``MSVC``, and ``AppleClang``
|
|
|
|
|
compilers that have only one frontend variant.
