We already detect `sizeof(void*)`. Detect the byte order as part of the same check. Issue: #21392

CMAKE_<LANG>_BYTE_ORDER
|
|
-----------------------
|
|
|
|
.. versionadded:: 3.20
|
|
|
|
Byte order of ``<LANG>`` compiler target architecture, if known.
|
|
If defined and not empty, the value is one of:
|
|
|
|
``BIG_ENDIAN``
|
|
The target architecture is Big Endian.
|
|
|
|
``LITTLE_ENDIAN``
|
|
The target architecture is Little Endian.
|
|
|
|
This is defined for languages ``C``, ``CXX``, ``OBJC``, ``OBJCXX``,
|
|
and ``CUDA``.
|
|
|
|
If :variable:`CMAKE_OSX_ARCHITECTURES` specifies multiple architectures, the
|
|
value of ``CMAKE_<LANG>_BYTE_ORDER`` is non-empty only if all architectures
|
|
share the same byte order.
