For cross-builds rely on `_POSIX_C_SOURCE` to decide if `poll()` is
supported, rather than just assuming it isn't.
This may still miss to detect `poll()` support, as seen for example with
Linux MUSL cross-builds.

(to test this case with cmake, with a false-negative.)

`poll()` detection snippet.

In Find modules with native pkg-config detection (libgsasl, libidn2,
libssh, libuv, nettle) use the C compiler flags returned by pkg-config.
Also use the library paths, and return the pathless library names.
Also:
- add these library paths to `libcurl.pc`/`curl-config`.
- fix libgsasl detection to use the detected header directory.
FindGSS already did this before this patch.
Fixes#14641Closes#14652
- add pkg-config-specific 'Found' message to the Find module.
- update non-pkg-config 'Found' message to show the flavour instead of
the library name. (= the first value listed after `REQUIRED_VARS`)
- delete extra 'Found' message from `CMakeLists.txt`.
- rename internal result variables to match with default pkg-config
names, in preparation of introducing them in other Find modules:
- `GSS_LINK_DIRECTORIES` -> `GSS_LIBRARY_DIRS`
- `GSS_LINKER_FLAGS` -> `GSS_LDFLAGS`
- `GSS_COMPILER_FLAGS` -> `GSS_CFLAGS`
Ref: #14652Closes#14651
For: libgsasl, libidn2, libssh, libuv.
The new Find modules retain using `pkg-config` natively, not as a "hint"
for the CMake-native detection. Of the pre-existing Find modules, only
FindNettle, and FindGSS (with customized code) work this way. Align
detection code for the new modules and add version detection for the
CMake-native paths.
Also, add CMake-native detection for `libgsasl`.
The remaining outlier in `CMakeLists.txt` is GnuTLS, which has
a CMake built-in Find module, but which lacks `pkg-config` support,
required for vcpkg. It remains unchanged.
Another part-outlier is `libssh`, which keeps requiring the trick
`find_package(libssh CONFIG QUIET)` for reasons I could not yet figure
out.
Closes#14555
Limits `pkg-config` to UNIX and MSVC with vcpkg, by default. Compared to
curl 8.9.1, this unlocks `pkg-config` on MSVC with vcpkg.
This condition might be updated in the future depending on where
`pkg-config` can be useful without breaking things. (e.g. to non-cross
MINGW, or all MINGW).
In the meantime everyone is free to override the default and test their
build with `pkg-config` by setting the `CURL_USE_PKGCONFIG=ON` CMake
option.

Our convention for naming Find modules (the part after the `Find`
prefix, also called as 'package name') is:
Always start with uppercase. Follow with lowercase, unless there is
a clear preference for a stylized name. E.g. the project itself uses it
that way with a matching `<Name>Config.cmake` file, or we use it that
way elsewhere, or the name is an acronym.

- `message(STATUS "Found <NAME> ...` in Find modules.

Closes#14599
-Wformat-overflow is not a warning that we want enabled as it does not
help us. It can only bring us false positives since it warns on bad uses
of sprintf and vsprintf ("that might overflow the destination buffer").
Two functions we explicitly ban in curl code.
The only way this flag triggers warnings in curl code is false positives
for functions we have marked with the CURL_PRINTF() macro.
Further: it seems -Wformat-trunaction option might in turn also enable
-Wformat-overflow, so if this second option is used, we need to
explicitly set -Wno-format-overflow - not just skip setting
-Wformat-overflow.

Prefer `pkg_check_modules()` over `pkg_search_module()`.
`pkg_check_modules()` logs a line when there is a hit, and also warnings
if a sub-dependency is missing. In `QUIET` mode, both are silent.
The extra info is useful to see if a detection happened via
`pkg-config`.
Keep `pkg_search_module()` in `FindGSS`. We pass two dependencies
there and we want to keep stopping on the first one.

Add option to control whether to use `pkg-config` to detect
dependencies. Curl's CMake uses `pkg-config` by default for all targets
except for MSVC without vcpkg.
With the CMake option `-DCURL_USE_PKGCONFIG=ON` you can override it to
use `pkg-config` always.
If `pkg-config` is causing issues, e.g. in cross-builds or other cases,
`-DCURL_USE_PKGCONFIG=OFF` disables all use of `pkg-config`.
Also add it to `curl-config.cmake`. Not yet used, but will be once curl
starts referencing any curl-specific `Find*` module from this public
script.
Follow-up to 9dfdc6ff42#14483Closes#14504
Before this patch, `pkg-config` was used for `UNIX` builds only (with
a few exceptions like wolfSSL, libssh, gsasl, libuv). This patch extends
`pkg-config` use to all envs except: `MSVC` without vcpkg. Meaning MSVC
with vcpkg will now use it. Also mingw on Windows.
Also apply the new condition to options where `pkg-config` was used
unconditionally (= for all targets). These are:
`-DCURL_USE_WOLFSSL=ON`, `-DCURL_USE_LIBSSH=ON`,
`-DCURL_USE_GSASL=ON` and `-DCURL_USE_LIBUV=ON`
This patch may still cause regressions for cross-builds (e.g. mingw
cross-build from Unix) and potentially other cases. If that happens, we
recommend using some of these methods to explicitly disable `pkg-config`
when using CMake:
- CMake option: `-DPKG_CONFIG_EXECUTABLE=`
(or `-DPKG_CONFIG_EXECUTABLE=nonexistent` or similar)
This is similar to the (curl-specific) `PKG_CONFIG` env for autotools.
- export env: `PKG_CONFIG_LIBDIR=`
(or `PKG_CONFIG_PATH`, `PKG_CONFIG_SYSROOT_DIR`,
or the CMake-specific `PKG_CONFIG`)
We may improve control over this in a future patch, also allowing opting
in MSVC (without vcpkg).

The oldest cmake supported by curl is v3.7.0, which already has such
guard (using `PKG_CONFIG_EXECUTABLE`) inside `pkg_check_modules()`. The
advantage of leaving that guard to CMake is that it will define/reset
all output variables, while the manual guard doesn't do this and also
leaves for example `NETTLE_FOUND` undefined.
Delete the single use of this guard from the recently added `nettle`
detection, where I included it by accident. Then possibly re-introduce
it universally if we find it useful after more evaluation.
