  As expected, the problem is in the kirogi code. Read the ECMAddAppIcon doc:
  
    # The given icons, whose names must match the pattern::
    #
    #   <size>-<other_text>.png
  
  and now look at the kirogi code:
  
    file(GLOB ICONS_SRCS "${CMAKE_CURRENT_SOURCE_DIR}/../data/icons/*apps-kirogi.svg")
    ecm_add_app_icon(kirogi_SRCS ICONS ${ICONS_SRCS})
  
  The warning about Windows is expected.
  
  Now about Apple: if a .svg or .svgz is passed to ecm_add_app_icon, ksvg2icns (if found) will create the icons bundle.
  
  The solution is not hiding the warning when the macro is called on different platform but fixing the condition.
  
  Suggestion: After landing D26751 <https://phabricator.kde.org/D26751>, add a `else()` block to `if (NOT (ext STREQUAL "svg" OR ext STREQUAL "svgz"))` where you `set(_ecm_add_app_icon_svg_icons TRUE)`
  and change:
  
    if (NOT (mac_icons OR mac_sidebar_icons))
  
  to:
  
    if (NOT (mac_icons OR mac_sidebar_icons) AND NOT _ecm_add_app_icon_svg_icons)
  
  Since ksvg2ico doesn't create the sidebar icons it can be further improved but at least you won't see a warning if you call ecm_add_app_icon with only svg files.
  
  You will only get the warning about the broken behaviour on Windows.
  
  Now another note: kirogi doesn't provide any png icon, this is also bad on Linux. Please create png icons and install them in the hicolor namespace.
