### libical Dependencies

#### Required

CMake-4.3.2

#### Recommended

GLib-2.88.0 (with GObject Introspection), libxml2-2.15.3, and Vala-0.56.19 (both required for GNOME)

#### Optional

Doxygen-1.17.0 (for the API documentation), Graphviz-14.1.5 (for the API documentation), GTK-Doc-1.36.1 (for the API documentation), ICU-78.3, PyGObject-3.56.2 (for some tests), and Berkeley DB (deprecated)

## Installation of libical

Install libical by running the following commands:

    mkdir build &&
    cd    build &&

    cmake -D CMAKE_INSTALL_PREFIX=/usr  \
          -D CMAKE_BUILD_TYPE=Release   \
          -D SHARED_ONLY=yes            \
          -D ICAL_BUILD_DOCS=false      \
          -D GOBJECT_INTROSPECTION=true \
          -D ICAL_GLIB_VAPI=true        \
          .. &&
    make -j1

If you have Doxygen-1.17.0, Graphviz-14.1.5, and GTK-Doc-1.36.1 installed and wish to build the API documentation, you should remove the `-D ICAL_BUILD_DOCS=false` switch and issue:

    make docs

To test the results, issue: make test.

Now, as the `root` user:

    make install

If you have built the API documentation, install by issuing, as `root` user:

    install -vdm755 /usr/share/doc/libical-3.0.20/html &&
    cp -vr apidocs/html/* /usr/share/doc/libical-3.0.20/html

## Command Explanations

`-D CMAKE_BUILD_TYPE=Release`: This switch is used to apply higher level of the compiler optimizations.

`-D SHARED_ONLY=yes`: This switch is used in order to only build the shared libraries.

`-D ICAL_BUILD_DOCS=false`: This switch prevents building the GTK documentation. Remove if you want to build the documentation.

`-D GOBJECT_INTROSPECTION=true`: This switch is used to generate GObject metadata bindings.

`-D ICAL_GLIB_VAPI=true`: This switch is used in order to build bindings for Vala-0.56.19.

`-D USE_BUILTIN_TZDATA=yes`: This switch is used in order to build using your own timezone data.
