.. versionadded:: 4.1
MSVC is not an assembler for language ASM.
When enabling the ``ASM`` language, CMake considers C compiler drivers
as assembler candidates. CMake 4.0 and below accidentally selected
MSVC's ``cl`` compiler as the ``CMAKE_ASM_COMPILER``, allowing the ``ASM``
language to be enabled on Windows even though ``cl`` does not support
assembler sources. CMake 4.1 and above prefer to reject ``cl`` as an
assembler candidate, but some existing projects unconditionally enable
``ASM`` on Windows even though they add no assembler sources. This
policy provides compatibility for such projects to allow them to
configure as before.
The ``OLD`` behavior for this policy is to successfully enable ``ASM``
even if ``cl`` is the only available candidate. The ``NEW`` behavior
for this policy is to not consider ``cl`` as a candidate assembler
for the ``ASM`` language.
