No need to save a few characters on formal parameters.

Use this occasion to correct $<PLATFORM_ID:comp>:
the parameter is a platform_id, not a compiler_id.

target, and ``0`` otherwise. If this expression is used while evaluating
the link implementation of a target and if any dependency transitively
increases the required :prop_tgt:`C_STANDARD` or :prop_tgt:`CXX_STANDARD`
for the 'head' target, an error is reported. See the
:manual:`cmake-compile-features(7)` manual for information on
compile features and a list of supported compilers.
``$<COMPILE_LANGUAGE:lang>``
``1`` when the language used for compilation unit matches ``lang``,
``$<COMPILE_LANGUAGE:language>``
``1`` when the language used for compilation unit matches ``language``,

compile definitions, and include directories for source files of a
particular language in a target. For example:
