[iOS] Fails to build in projects with dynamic framework linkage

[birdofpreyru]

On iOS, if the host app uses use_frameworks! :linkage => :dynamic in its Podfile, the library fails to build at its linkage step, saying symbols from lighttpd are not available.

A workaround is to enforce static linkage for this library, by adding to the Podfile

  pre_install do |installer|
    installer.pod_targets.each do |pod|
      if ['ReactNativeStaticServer'].include?(pod.name)
        def pod.build_type; Pod::BuildType.static_library; end
      end
    end
  end

Unfortunately, (1) my current understanding of Xcode builds for iOS (with additional Cmake build and linkage of C library) is not sufficient for a proper, quick fix. of the issue; and (2) Podfiles (Cocoapods) are already deprecated, and RN ecosystem moves to Swift package manager; I guess, this will anyway require another learning of new stuff and re-work of the library build... thus, most probably I'll wait for RN getting rid of Cocoapods, and then will look into upgrading the library build setup.

P.S.: Also we have PR #151 submitted a while ago, which changes the build setup to use pre-build iOS lighttpd server as xcframework — I have not looked into it, as it does stuff I had no previous experience with, but now it feels like it might be also the proper solution of this issue, thus I should finally look into it.

Note: react-native-google-mobiles-ads seemingly is able to switch itself between dynamic and static linking, looking at the flag set by the host project Podfile ($RNGoogleMobileAdsAsStaticFramework = true) — I guess, as the current workaround here, I should be able to copy-paste what they do.
