Create Cemu .app bundle for macOS

[emiyl]

This PR:

• Creates a .dmg file when building releases, containing a Cemu.app bundle and an alias to /Applications
• Disables portable mode when compiling for macOS, using ~/Application Support/Cemu instead, and Cemu.app/Contents/SharedSupport for default game profiles and langauge files
• Copies the MoltenVK dylib from the macOS build VM to the bundle, so it can be ran without installing anything from brew

This brings the macOS releases more in line with most other macOS apps.

While this does work, it's very sub-optimal because it relies on GitHub Actions to build the bundle. In addition, the built bundle does not include an Info.plist file. macOS expects all apps to have this file and for it to be populated with metadata.

Please consider using CMake build options instead.

Also, I don't believe you need to include MoltenVKShaderConverter.

Something along the lines of this, I don't have the iconset but it should be easy to create one based on a high quality base icon.

I also fixed working with resource files when using app bundles with this.

I'm not quite sure how this should all be put together, but this are small changes you can take as reference

Thank you for the feedback, I'm now using the CMake build system to generate the app bundle and I created this icon, which I think fits in pretty well with macOS. It uses Helvetica Neue instead of the original font.

hi Emiyl, thanks for your effort/work for bundling Cemu into Mac app. Probably you are aware of it, but a brief feedback: I still manually need to chmod Cemu app in Contents in order to run it. (at least on my Studio) Other than that I can not give the app permission to be able to read the folder where I store my game dump, the app is simply not showing up in data security settings where I can give the folder permission to it. (this could be because due to my lack of knowledge :-))

This should now be fixed.

Hmm that's odd. I get the prompt when opening to access my folders when opening the app, but not when I directly open the binary from the MacOS folder. Are you opening the .app bundle?

[DTibor1986]

Accessing the games folder is OK now, just needed to update my keys.txt in Application Support library. (sorry my mistake) As for the chmod, still necessary even with the latest build, compiled less than an hour ago.

It would be great to have the .app file into a .dmg like any other third party app for MacOS

[emiyl]

For releases, it will be packaged in .dmg

I see the issue :( Unfortunately I'm not sure. It's definitely running chmod on the binary before it's released as an artifact, but it doesn't seem to carry across.

It seems when using zip, file permissions are not preserved. Some other format must be used, I’ve seen good results with tar. Link

[galad87]

To create a zip that keeps all the right macOS bits you can use:

ditto -c -k --sequesterRsrc --keepParent

[emiyl]

I've worked around the permissions issue by just packaging the artifact in a dmg, and then mounting the dmg in the release actions.

[DTibor1986]

Hi Emiyl,

the dmg in latest nightly is working great, thank you!! :-) If it not a big request could you please make an app bundle with moltenVK 1.2 included?

[emiyl]

moltenvk 1.2 should already be included
