# GLibTools.cmake
#
# Provides functions to run glib tools.
#
# Functions:
#
# glib_mkenums(_output_filename_noext _enums_header _define_name)
# runs glib-mkenums to generate enumtypes .h and .c files from _enums_header.
# It searches for files in the current source directory and exports to the current
# binary directory.
#
# An example call is:
# glib_mkenums(camel-enumtypes camel-enums.h CAMEL_ENUMTYPES_H)
# which uses camel-enums.h as the source of known enums and generates
# camel-enumtypes.h which will use the CAMEL_ENUMTYPES_H define
# and also generates camel-enumtypes.c with the needed code.
#
# gdbus_codegen(_xml _interface_prefix _c_namespace _files_prefix _list_gens)
# runs gdbus-codegen to generate GDBus code from _xml file description,
# using _interface_prefix, _c_namespace and _files_prefix as arguments.
# The _list_gens is a list variable are stored expected generated files.
#
# An example call is:
# set(GENERATED_DBUS_LOCALE
# e-dbus-localed.c
# e-dbus-localed.h
# )
# gdbus_codegen(org.freedesktop.locale1.xml org.freedesktop. E_DBus e-dbus-localed GENERATED_DBUS_LOCALE)
#
# gdbus_codegen_custom(_xml _interface_prefix _c_namespace _files_prefix _list_gens _args)
# The same as gdbus_codegen() except allows to pass other arguments to the call,
# like for example --c-generate-object-manager
