I use CMake for my builds not the XCode GUI. I want to be able to build a single .app that contains both the GUI version and the command line version. I have seen products that ship both as part of the same .app (e.g. CMake) so this is clearly entirely possible, the 64k question is HOW? Right now I am building them as separate apps - lets call them DSS and DSSCL (*). The code base for each is in its own directory - each with its own CMakelists.txt file. My initial thoughts are to change the build for DSSCL so it doesn't create a bundle and then simply copy the DSSCL command and related .qm files into DSS.app/.../MacOS. However that's likely enough totally wrong, so how should I handle this please. As much detail as possible please, I am very new to macOS development -please don't assume knowledge of stuff that's second nature to you Many thanks David (*) Strictly they are DeepSkyStacker and DeepSkyStackerCL

My application uses a text file with an extension of .dssfilelist. On Linux I would register the Mime type and associate it with the application in the .desktop file. <?xml version="1.0" encoding="UTF-8"?> <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"> <mime-type type="text/dssfilelist"> <comment>DeepSkyStacker file-list file</comment> <glob pattern="*.dssfilelist" /> </mime-type> </mime-info> I believe that I need to add stuff to the Info.plist for my application, but I also understand that CFBundleTypeExtensions is deprecated. So please could you show me what I now need to add to the Info.plist file so that these files will be registered as "text/dssfilelist" type and associated with my application and to associate a .icns file with it?
