+You might need some other dependencies like:
+  * sigc++-3.0
+  * gtk4
+  * glibmm-2.68
+  * cairomm-1.16
+  * pangomm-2.48
+To build from source:
+<code bash>
+# Install mm-common
+sudo apt install mm-common
+# Build and install libsigc++3
+# https://github.com/libsigcplusplus/libsigcplusplus
+wget https://github.com/libsigcplusplus/libsigcplusplus/releases/download/3.2.0/libsigc++-3.2.0.tar.xz
+tar xzf libsigc++-3.2.0
+cd libsigc++-3.2.0
+cmake .
+./autogen.sh --prefix=/usr/local --enable-static
+make
+sudo make install
+# glibmm
+# https://gitlab.gnome.org/GNOME/glibmm
+wget https://gitlab.gnome.org/GNOME/glibmm/-/archive/2.70.0/glibmm-2.70.0.tar.gz
+tar xzf glibmm-2.70.0.tar.gz
+cd glibmm-2.70.0
+./autogen.sh --prefix=/usr/local --enable-static
+make
+sudo make install
+# cairomm
+# https://www.cairographics.org/releases/
+wget https://www.cairographics.org/releases/cairomm-1.16.1.tar.xz
+tar xBf cairomm-1.16.1.tar.xz
+cd cairomm-1.16.1
+./autogen.sh --prefix=/usr/local --enable-static
+make
+sudo make install
+# pangomm
+# https://gitlab.gnome.org/GNOME/pangomm
+wget https://gitlab.gnome.org/GNOME/pangomm/-/archive/2.50.0/pangomm-2.50.0.tar.gz
+tar xzf pangomm-2.50.0.tar.gz
+cd pangomm-2.50.0
+./autogen.sh --prefix=/usr/local --enable-static
+make
+sudo make install
+# gtkmm
+wget https://download.gnome.org/sources/gtkmm/4.6/gtkmm-4.6.0.tar.xz
+tar xBf gtkmm-4.6.0.tar.xz
+cd gtkmm-4.6.0
+./autogen.sh --prefix=/usr/local --enable-static
+make
+sudo make install
+</code>
+When compiling, use ''-std=c++20'' flag. When running, you may need to set LD_LIBRARY_PATH if you installed to a special prefix. Maybe able to add ''-static'' if you built all libs with ''--enable-static' configuration and a ''.a'' file is in the lib dir.
+<code bash>
+# Compile app with gtk4
+g++ main.cpp `pkg-config gtkmm-4.0 --cflags --libs` -std=c++20
+# Set path for shared library when running
+LD_LIBRARY_PATH=/usr/local/lib ./a.out
+</code>
+Here is a gtkmm hello world:
+<code cpp main.cpp>
+// gtkmm4 example
+// Compile with:
+// g++ main.cpp `pkg-config gtkmm-4.0 --cflags --libs` -std=c++20
+// Run with
+// LD_LIBRARY_PATH=/usr/local/lib ./a.out
+#include <gtkmm.h>
+class MyWindow : public Gtk::Window
+{
+public:
+  MyWindow();
+};
+MyWindow::MyWindow()
+{
+  set_title("Basic application");
+  set_default_size(200, 200);
+}
+int main(int argc, char* argv[])
+{
+  auto app = Gtk::Application::create("org.gtkmm.examples.base");
+  return app->make_window_and_run<MyWindow>(argc, argv);
+}
+</code>
