ecm_install_icons() should warn the developer in case the icon naming scheme is improper
ecm_install_icons() simply fails silently if the user does something like ecm_install_icons(ICONS someapp.png DESTINATION ${KDE_INSTALL_ICONDIR})
. It only accepts files in the format <size>-<group>-name.<extension>
.
This is well documented on the API website, but I think it should print something at install time to indicate when the filename scheme is wrong.
