# ECMGenerateQmlTypes
# -------------------
#
# Generates plugins.qmltypes files for QML plugins.
#
# ::
#
#   ecm_generate_qmltypes(<org.kde.pluginname> 1.3
#                         DESTINATION <${KDE_INSTALL_QMLDIR}/org/kde/pluginname>)
#
# Makes it possible to generate plugins.qmltypes files for the QML plugins that
# our project offers. These files offer introspection upon our plugin and are
# useful for integrating with IDE language support of our plugin. It offers
# information about the objects its methods and their argument types.
#
# The developer will be in charge of making sure that these files are up to date.
# The plugin.qmltypes file will sit in the source directory. This function will
# include the code that installs the file in the right place and a small unit
# test named qmltypes-pluginname-version that makes sure that it doesn't need updating.
#
#
# Since 5.33.0
