Subject: cmake: tidy-ups and rebase fixups
X-Git-Tag: curl-8_11_0~163
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=01a81579977b3872935d508e306a735f0568d113;p=thirdparty%2Fcurl.git

cmake: tidy-ups and rebase fixups

- limit `SIZEOF_SA_FAMILY_T` detection to non-Windows.
- make sure `sys/socket.h` exists before detecting `SIZEOF_SA_FAMILY_T`.
- limit `mach_absolute_time()` detection to `APPLE`. Drop from Windows
  pre-cache.
- skip `HAVE_LIBSOCKET` detection for Windows, drop pre-cached value.
- drop redundant pre-cached `HAVE_LIBZ` for Windows.
- `curl_required_libpaths()`: stop accepting multiple arguments.
  To prepare for `CMAKE_REQUIRED_LINK_DIRECTORIES` support.
  Follow-up to 7bab201abe3915a0167c002f9308950cb8a06e4b #15193
- GSS: fix recent rebase mistakes:
  - fix variable name.
  - do not add a header twice.
  Follow-up to 91d451b48809f20415ba8627786f5d4f5aaf8bfe #15157
- GSS: quote a variable.

Closes #15271
