+Subject: [PATCH 1/3] Find qmlimportscanner in macdeployqt via environment
+
+The qmlimportscanner tool is provided by qtdeclarative. Because of the
+modularized installation in Nix, it can not be found via the usual
+mechanisms.  Also, hard-coding it like we do for Qt5 would also not
+work, as it would require making qtbase depend on qtdeclarative.
+
+Here we add an option to provide its location via the environment.
+While this means macdeployqt does not work out of the box, it provides
+a workaround for users.

+Subject: [PATCH 2/3] Check in the QML folder of this library does actually
+ exist
+
+In a modularized installation, this folder will be the location where
+`qtbase` itself is installed, but `qtbase` does not have any QML
+code, and `qmlimportscanner` will complain that it does not exist.
