[libzip] build failure with GCC14 : error: implicit declaration of function ‘getpid’ [-Wimplicit-function-declaration] #1194

Hello, I cannot compile flycast with gcc14 (gcc12 compile without issue) on my gentoo system.

Maybe libzip needs a more recent version ? There is a pull request to update some deps here (unfortunately libzip is not in it) : https://github.com/libretro/flycast/pull/952

Thanks for reading.

Thanks flyinghead, I didn't realize there was a flycast_libretro project in CMakeLists.txt in your repo ! I'll adjust my gentoo ebuild and try that. (edit: It compiles fine with gcc14 now :D )
