CMake shared libraries error: `shared library dependency not found in library path`

I am compiling a large CMake code base to Emscripten, where certain libraries must be compiled into dynamically linked libraries. Since Emscripten doesn't support `add_library(... SHARED ...)` by default, I am trying to use [this workaround](https://github.com/emscripten-core/emscripten/issues/15276#issuecomment-1039349267) (another approach would be to use `add_executable(...)` with `-sSIDE_MDOULE=1` - but that would require refactoring of a very large number of CMake files, which I want to avoid).

That approach **almost** works, except for this: I am building two shared libraries, `A` and `B`. `A` defines that `B` should be added as a linked library:

```cmake
# A/CMakeLists.txt
set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS TRUE)

add_library(A SHARED ${sources})
set_target_properties(A PROPERTIES SUFFIX ".wasm")
target_link_options(A PRIVATE "-sSIDE_MODULE=1")
target_compile_options(A PRIVATE "-sSIDE_MODULE=1")

set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS FALSE)
````

```cmake
# B/CMakeLists.txt
set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS TRUE)

# ... same as A
target_link_libraries(B A) # Link library A into B

set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS FALSE)
````

With that, the build fails with this error:
```
em++: error: /project/libB.wasm: shared library dependency not found in library path: `libA.wasm`. (library path: ['/project/runtime/output/wasm32-emscripten/build/vcpkg_installed/wasm32-emscripten/lib', '/project/runtime/output/wasm32-emscripten/build/vcpkg_installed/wasm32-emscripten/debug/lib', '/emsdk/upstream/emscripten/cache/sysroot/lib/wasm32-emscripten/pic']
```

Is there a way to modify this library path, mentioned in the error message? Has anyone managed to get this to work? Any help would be much appreciated!
