Miikka Heikkinen 3ac3b61727 QmlDesigner: Ifdef nanotrace.h out if nanotrace lib is not included
Nanotrace headers are not exported to build dir at all if the feature
is disabled, so runtime puppet build can't find them. We have to
ifdef out the header include and define the required macros as empty
in puppet.
