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.
