* [CMake] Only build SwiftSyntax if building SDK overlays SwiftSyntax depends on Foundation, which depends on the SDK overlays being built. However, the existing build configuration tried to build SwiftSyntax even if the SDK overlays were not built. Ensure we're building overlays before building SwiftSyntax, and guard tests with an sdk_overlay test. * Remove TODO comment
