Drop the icon file extension. This fixes the desktop file validation
message:
"CMakeSetup32.png" for key "Icon" in group "Desktop Entry" is an icon
name with an extension, but there should be no extension as described in
the Icon Theme Specification if the value is not an absolute path

The Encoding key is now deprecated by the FreeDesktop standard and all
strings are required to be encoded in UTF-8. This desktop entry
explicitly specified an Encoding of UTF-8, which is harmless but no
longer necessary. See
http://standards.freedesktop.org/desktop-entry-spec/1.0/apc.html
for details. Patch from Modestas Vainius. See issue #9659.
