How to run the samples on M1 macOS on 'arm64' architecture? Issues with resources? #509

Hi, I want to test out Ultralight on my M1 macOS. I tried both 1.4.x and v1.4.0b, and it successfully compiles, but launching any .app instantly crashes with this error:

Termination Reason:    Namespace DYLD, Code 1 Library missing
Library not loaded: @rpath/libUltralightCore.dylib

I was able to fix it by manually modifying the Info.plist for the apps like in ultralight-sdk-latest-mac-arm64/build/samples/Sample 8 - Web Browser/Sample8.app/Contents/Info.plist by adding:

<key>DYLD_LIBRARY_PATH</key>
<string>/Users/dima/Downloads/ultralight-sdk-latest-mac-arm64/bin/</string>

Now, it does not crash instantly, but reports this error:

Failed to load ICU data (icudt67l.dat) from the FileSystem interface. Make sure that you've defined a FileSystem and the file can be found in the correct path. Aborting.

and this:

Could not load resource: resources/icudt67l.dat, FileSystem::FileExists() returned false.

Does anyone know how to fix this? Thanks!

I'm having the same issue.

The issue happens on all OS, there is probably a bug in cmake/build scripts that causes the resources not be copied where they need to be, if you copy them manually it works

Where should they be copied to exactly? I've copied the 'resources' folder from ultralight-sdk-latest-mac-arm64/build to ultralight-sdk-latest-mac-arm64/build/samples/Sample 1 - Render to PNG

Ultralight filesystem works from ./assets/ by default, so that would be ./assets/resources/icudt67l.dat (relative to CWD of the process). This works on my machine. But looking at the code it might be different on macOS based on its app conventions. See ultralight::Settings::file_system_path and ultralight::Config::resource_path_prefix

It works!!!!!

Thank you so much for taking the time to help.
