glibmm@2.66 for Mac

glibmm is a C++ wrapper library provided by the GTK project that wraps GLib's C interface into classes and functions more idiomatic to C++, allowing developers to use the infrastructure offered by GLib in an object-oriented way. It mainly addresses the problems of type unsafety and cumbersome code that arise when calling C-style GLib APIs directly in C++ projects, making it suitable for developers building desktop applications or low-level tools within the GTK ecosystem using C++. When it appears as a command-line tool, it is typically used in conjunction with a build system to help projects correctly include and link against glibmm. It should be noted that it is not a standalone application but a development dependency, and ordinary users generally do not run it directly.
