Raw Blame History

From 9ee52eea768af39f4ccbc1939d1385d70bb0ef37
From: Ben Barham <ben_barham@apple.com>
Date: Tue, 16 May 2023 16:25:36 -0700
Subject: [PATCH 1/4] [CMake] Updates to allow inclusion using FetchContent
Various updates that allow swift-syntax to be included using
FetchContent.
Mostly this is just not replacing `target_link_libraries` since that is
a global replacement, but we also now use a couple of variables from the
swift if they're set (eg. `SWIFT_HOST_LIBRARIES_DEST_DIR` and
`SWIFT_HOST_MODULE_TRIPLE`).
