CMP0129
-------
.. versionadded:: 3.23
Compiler id for MCST LCC compilers is now ``LCC``, not ``GNU``.
CMake 3.23 and above recognize MCST LCC compiler as a different from ``GNU``,
with its own command line and set of capabilities.
CMake now prefers to present this to projects by setting the
:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``LCC`` instead
of ``GNU``. However, existing projects may assume the compiler id for
LCC is ``GNU`` as it was in CMake versions prior to 3.23.
Therefore this policy determines for MCST LCC compiler 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 ``GNU`` (and set
:variable:`CMAKE_<LANG>_COMPILER_VERSION` to the supported GNU compiler version.)
``NEW`` behavior for this policy is to use compiler id ``LCC``, and set
:variable:`CMAKE_<LANG>_SIMULATE_ID` to ``GNU``, and
:variable:`CMAKE_<LANG>_SIMULATE_VERSION` to the supported GNU compiler version.
.. |INTRODUCED_IN_CMAKE_VERSION| replace:: 3.23
.. |WARNS_OR_DOES_NOT_WARN| replace:: does *not* warn by default
.. include:: include/STANDARD_ADVICE.rst
See documentation of the
:variable:`CMAKE_POLICY_WARNING_CMP0129 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
variable to control the warning.
