Define the `Python_DEFINITIONS` variable for the support of free
threaded Python developments on Windows.
This is a complement to commit 9a0dee7257 (FindPython: Add support for
free threaded python, 2024-05-30).
Alpine Linux has the `iconv.h` belonging to the builtin `iconv` library
provided by musl C library in the standard directory (`/usr/include`).
However, when installing the GNU libiconv APK package (`gnu-libiconv`),
the GNU `libiconv` library has header located in
`/usr/include/gnu-libiconv` subdirectory. Fix finding the header
matching the `libiconv` library.
Issue: #24695
Fix commit df551ee538 (FindPython: fix NumPy detection when Intel MKL
library is installed, 2024-03-20, v3.30.0-rc1~361^2) by setting
`MKL_ENABLE_INSTRUCTIONS` to `SSE4_2`, but only if
`MKL_ENABLE_INSTRUCTIONS` is not set in the calling environment.
Fixes: #26240
`xlC` now warns "Additional optimization may be attained by recompiling
and specifying MAXMEM option" on `cmExportPackageInfoGenerator`.
Add the suggested option.
`cmake_path(GET "foo/.." STEM out)` is supposed to set `out` to `".."`,
the entire `cmake_path(GET "foo/.." FILENAME)` result.
However, the `GetNarrowStem()` logic in `cmCMakePath` was lacking
the `.` and `..` special-casing logic present in other methods.
As a result, it would erroneously trim the second `.` off of a stem
of `..` and return only `.`.
This caused the result of `cmake_path(GET "foo/.." STEM)` to be `"."`.
Making the standard empty-or-.-or-.. checks and bailing out early
fixes the result of `cmCMakePaths{".."}.GetNarrowStem()`.
Fixes: #26235

If a single-value keyword is followed by an empty string, the
command unsets the variable for that keyword instead of setting
it to the empty string. This is inconsistent and unexpected. Add
policy CMP0174 which ensures the variable for a single-value
keyword is always set when any value is given, not just for a
non-empty value.
The new CMP0174 policy only affects the PARSE_ARGV form of
cmake_parse_arguments. The older form silently drops all empty
string arguments before processing the argument list.
Fixes: #25972
`NDK_PROC_*_ABI` and `NDK_ARCH_*_ABI` were removed in the Android
NDK 27 but will be reintroduced in the Android NDK 27b:
* https://github.com/android/ndk/issues/2049
* https://android-review.googlesource.com/c/platform/ndk/+/3196345
Both are only used when `CMAKE_ANDROID_ARCH_ABI` is NOT given. But
currently the existence is also checked when `CMAKE_ANDROID_ARCH_ABI`
is given. So we move the checks to the position they are required.
