###
#
# Function and support code for adding a Calamares module (either a Qt / C++ plugin,
# or a Python module, or whatever) to the build.
#
# # Usage
#
# The public API is one single function:
#
# - calamares_add_module_subdirectory(subdirectory [skiplistvar])
# Adds a given *subdirectory* to the modules list, building the
# module that is there. The *subdirectory* must contain a `module.desc`
# (generally non-C++ modules) or a `CMakeLists.txt` (for C++ modules,
# or special cases). The module is assumed to be named after the
# (last component of) the subdirectory.
#
# If the module would be skipped (by the global SKIP_MODULES setting
# or a USE_* setting) or the module itself sets a reason to skip
# via the calamares_skip_module() function, the module is added to
# the list of skipped-modules in *skiplistvar*. If no variable is
# given, the reason is set in the parent scope variable
# SKIPPED_MODULES . Do **not** use SKIPPED_MODULES as the name of
# *skiplistvar*, things will get weird.
#
# Do note that the name of a module must be the same as the name of
# the directory containing it (as documented in src/modules/README.md).
# This applies to both C++ and Python modules, and allows the use of
# the subdirectory as a proxy for the module name inside.
