Hello all, When making a pure Swift bundle Xcode automatically copies `libswiftCore.dylib` as follows.
``` ./Tests/SwiftOnly/Debug/SwiftOnly.app └── Contents ├── Frameworks │ └── libswiftCore.dylib ├── Info.plist ├── MacOS │ └── SwiftOnly ├── PkgInfo └── Resources └── libswiftRemoteMirror.dylib ``` When I try to run the output I get a dynamic linking error. I can reproduce this by adding MACOSX_BUNDLE to `./Tests/SwiftOnly/CMakeLists.txt` (in the CMake source tree) in `add_executable` and trying to run the result. ``` % ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: .../Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly Reason: image not found zsh: abort ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly ``` It seems that the rpath should be set to `@loader_path/../Frameworks`. I am not a Swift maestro so not exactly sure on the details of how this works. After running `install_name_tool -add_rpath "@loader_path/../Frameworks" ./Tests/SwiftOnly/Debug/SwiftOnly.app/Contents/MacOS/SwiftOnly` it runs fine. Does anyone have any idea what to do? Is it a missing CMake Swift feature? We are currently working around it by manually adding the rpath with a cmake step.
