.ts files not processed

As per instructions in bug 578 I removed my custom build step and changed the project property settings for ts files to run lrelease.

When I now try to build I get:

1>------ Build started: Project: DeepSkyStacker, Configuration: Debug x64 ------

1>rcc i18n\translations.qrc

1>moc dsseditstars.h

1>moc dssselectrect.h

1>moc dsstoolbar.h

1>moc ExplorerBar.h

1>moc IntermediateFiles.h

1>moc OutputTab.h

1> RCC: Error in 'C:\Users\amonra\Documents\GitHub\DSS\DeepSkyStacker\i18n\translations.qrc': Cannot find file 'DSS.ca.qm'

1>moc PostCalibration.h

1>C:\Users\amonra\AppData\Local\QtMsBuild\qt_globals.targets(269,5): error MSB4181: The "QtRunWork" task returned false but did not log an error.

1>Done building project "DeepSkyStacker.vcxproj" – FAILED.

And it doesn’t appear to run lrelease to create the qm files?

I'll attach the project file

I can take a binary trace of msbuild if wanted?
