How cocoapods detect static/dynamic framework for correct integration - https://github.com/CocoaPods/CocoaPods/blob/master/lib/cocoapods/xcode/linkage_analyzer.rb
How this implemented in kotlin plugin - https://github.com/JetBrains/kotlin/blob/master/libraries/tools/kotlin-gradle-plugin/src/main/kotlin/org/jetbrains/kotlin/gradle/targets/native/tasks/CocoapodsTasks.kt#L209

now dummy generation task support dynamic frameworks too, so we can just use kotlin plugin's version
