#
# Where to start
# ---------------------------------------------------------
#
# If you plan to modify the build system there are several places to look to do what you want.
#
# cmake/IrccdOptions.cmake    - User definable options.
# cmake/IrccdPackage.cmake    - Package creation.
# cmake/IrccdSystem.cmake    - Contains some platforms checks and compile flags.
# cmake/IrccdVersion.cmake    - Defines the Irccd version and its plugins.
# cmake/check            - Platform checks in separate files.
# cmake/function        - Custom functions.
# cmake/installer        - Some files for the QtIFW installer.
# cmake/internal        - Some internal files (e.g. the sysconfig.h)
# cmake/packages        - Additional find_package modules.
#
# Build system is then processed in different directories:
#
# contrib            - User contributions not maintained by irccd authors.
# doc                - The documentation process.
# extern            - External libraries.
# lib                - The irccd library
# irccd                - The irccd executable.
# irccdctl            - The irccdctl utility.
# plugins            - Official irccd plugins.
# tests                - The unit tests.
# win32                - Additional files for Windows platform.
