How do you include some cinterop headers in a library? I've added the headers like this

linuxX64 {
    val main by compilations.getting
    main.cinterops.create("x11") {
        defFile("src/linuxX64Main/cinterop/x11.def")
        compilerOpts.add("-I" + rootDir.resolve("include"))
    }
}

library compiles fine, and published to mavenLocal fine, but when some other project add it as a dependency and runs the linker, it produces the following

> Task :linkReleaseExecutableLinuxX64
e: C:\Users\Animesh\.konan\dependencies\msys2-mingw-w64-x86_64-clang-llvm-lld-compiler_rt-8.0.1/bin/ld.lld invocation reported errors

Don't the c-interop symbols get shipped with the artifact?

Presumably a dynamic library is being used. If that is the case then each project using the library will need to have its own def file that supplies the compilerOpts, linkerOpts, and headers. Note that compilerOpts, and linkerOpts might differ between the library, and the projects using the library.
