[CMake] WebKitSwift fails to build when the deployment target is older than
the SDK
https://bugs.webkit.org/show_bug.cgi?id=327592
rdar://190055833
Reviewed by Pascoe.
With -explicit-module-build, the Swift driver builds Clang modules for the SDK
version unless -clang-target is given. On a host with a newer SDK,
WebKitSwift's Clang importer therefore saw the new SDK as the minimum OS
version, while its
Swift compilation conditions (WebKit.platform-swift-args.resp) were derived for
the deployment target version. Therefore, headers and Swift code disagreed on
HAVE()/ENABLE()
values gated between the two versions.
Swift targets set up through
WEBKIT_SETUP_SWIFT_AND_GENERATE_SWIFT_CPP_INTEROP_HEADER
already pass -clang-target ${CMAKE_Swift_COMPILER_TARGET}. WebKitSwift is
configured by hand, so pass it there too.
