Trying out the ‘qt58’ part, snapcraft complains:
Issue while loading plugin: properties failed to load for qt58: The 'configflags' property does not match the required schema: [...] has non-unique elements
The reason for this is that the part tries to pass multiple
-skip arguments, which should be followed by a module name. This is impossible today, as
snapcraft seems to require the
configlags property to have unique entries.
snapcraft really impose that restriction?
