A modern programming language that makes developers happier.

kotlinlang

I have a multi-module Kotlin Multiplatform library for Android+iOS+tvOS that looks something like the following:
```MyProject
├── Library
├── Library-common
├── Library-submodule
└── Library-submodule-with-cinterops # has a cinterop def for a native dependency, let's call it Foo```
The idea is that Library depends on `Library-submodule` and `Library-submodule-with-cinterops`, both of which depend on `Library-common`. All is working fine, with the exception of the `Library-submodule-with-cinterops`. I can build that module in isolation, which generates the .aar, .framework files, and .klibs, but when I build `Library`, the linker fails with the following:
```The /Applications/Xcode <http://11.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld|11.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld> command returned non-zero exit code: 1.
output:
ld: framework not found Foo```
I’m not sure why `-framework Foo` is being added to the `ld` command (executed as part of `:Library:linkReleaseFrameworkApple`), I’m guessing I need to tell the linker where to find it, but I’m not sure how to go about it. Does anyone have any pointers for how I might fix it?

I’ve spent a bit more time debugging this.

The `Library-submodule-with-cinterops` is defined as a dependency of `commonMain` like so:

```api project(":Libary-submodule-with-cinterops")```
If I add the following to the `framework` options in `Library/build.gradle`:

```export project(':Libary-submodule-with-cinterops')```
I get the following output during `:Library:linkDebugFrameworkApple` (snipped for brevity):

```&gt; Task :Library:linkDebugFrameworkApple FAILED
