Detailed Description

Platform-specific symbol visibility macros.

ZXC_EXPORT, ZXC_NO_EXPORT and ZXC_DEPRECATED decide which symbols leave the shared library.

• Define ZXC_STATIC_DEFINE when building or consuming ZXC as a static library: it drops the import/export annotations entirely.
• Building the shared library, the CMake target defines zxc_lib_EXPORTS for you, which selects dllexport / visibility("default").
• Consuming it, neither macro is defined, so the header picks visibility("default") on ELF and no annotation on Windows.

On Windows dllimport is opt-in via ZXC_DLL_IMPORT, because an unannotated declaration still links against a DLL (through a call thunk), while dllimport against a static library fails on unresolved __imp_zxc_*. CMake, Meson and pkg-config set the right macro for you.
