#
# Generally, this CMakeLists.txt will find all the dependencies for Calamares
# and complain appropriately. See below (later in this file) for CMake-level
# options. There are some "secret" options as well:
#
#   SKIP_MODULES    : a space or semicolon-separated list of directory names
#                     under src/modules that should not be built.
#   USE_<foo>       : fills in SKIP_MODULES for modules called <foo>-<something>
#   WITH_<foo>      : try to enable <foo> (these usually default to ON). For
#                     a list of WITH_<foo> grep CMakeCache.txt after running
#                     CMake once. These affect the ABI offered by Calamares.
#                       - PYTHON (enable Python Job modules)
#                       - QML (enable QML UI View modules)
#                       - PYTHONQT # TODO:3.3: remove
#   BUILD_<foo>     : choose additional things to build
#                       - TESTING (standard CMake option)
#                       - SCHEMA_TESTING (requires Python, see ci/configvalidator.py)
#   DEBUG_<foo>     : special developer flags for debugging
#
# Example usage:
#
#   cmake . -DSKIP_MODULES="partition luksbootkeycfg"
#
# One special target is "show-version", which can be built
# to obtain the version number from here.

# Options for the calamares executable
option( WITH_KF5Crash "Enable crash reporting with KCrash." ON )  # TODO:3.3: WITH->BUILD (this isn't an ABI thing)

# Possible debugging flags are:
#  - DEBUG_TIMEZONES draws latitude and longitude lines on the timezone
#    widget and enables chatty debug logging, for dealing with the timezone
#    location database.
#  - DEBUG_FILESYSTEMS does extra logging and checking when looking at
#    partition configuration. Lists known KPMCore FS types.
#  - DEBUG_PARTITION_UNSAFE (see partition/CMakeLists.txt)
#  - DEBUG_PARTITION_LAME (see partition/CMakeLists.txt)


### USE_*
#
# By convention, when there are multiple modules that implement similar
# functionality, and it only makes sense to have **at most one** of them
# enabled at any time, those modules are named <foo>-<implementation>.
# For example, services-systemd and services-openrc.
#
# Setting up SKIP_MODULES to ignore "the ones you don't want" can be
# annoying and error-prone (e.g. if a new module shows up). The USE_*
# modules provide a way to do automatic selection. To pick exactly
# one of the implementations from group <foo>, set USE_<foo> to the
# name of the implementation. If USE_<foo> is unset, or empty, then
# all the implementations are enabled (this just means they are
# **available** to `settings.conf`, not that they are used).
#
# To explicitly disable a set of modules, set USE_<foo>=none
# (e.g. the literal string none), which won't match any of the
# modules but is handled specially.
#
# The following USE_* functionalities are available:
#  - *services* picks one of the two service-configuration modules,
#    for either systemd or openrc. This defaults to empty so that
#    **both** modules are available.

# TODO:3.3 With newer CMake, move HOMEPAGE_URL to the project()call
