Installation of libical

Prepare libical by running the following commands: 

cmake -B build -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
cmake --build build -j1

To test the results, issue: 

cd build
make test

Now Install, as the root user: 

cmake --install build

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-0.56.18.

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