[WangWeiLin-MV]

Fix #42659, error with poptconfig.c:108:9: error: implicit declaration of function ‘glob_pattern_p’ [-Wimplicit-function-declaration] on Ubuntu 24.

Repro with GCC 14, suppress it to fix.

Checklist

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

Test

The port installation tests pass with the following triplets:

• x64-linux

Did you check if the declaration could be pulled in with a missing #include <...>?

The warning seems to be treated as an error. Should the port disable -Werror instead of disabling a particular warning?

[WangWeiLin-MV]

Port run pass with test:

#include "popt.h"
#include <iostream>

int main(void) {
    std::cout << "libpopt" << std::endl;
    std::cout << POPT_OPTION_DEPTH << std::endl;
    poptContext context = poptGetContext(NULL, 0, 0, NULL, 0);
    poptFreeContext(context);
    return 0;
}

The warning seems to be treated as an error. Should the port disable -Werror instead of disabling a particular warning?

Build pass after adding the options.
