+Subject: [PATCH] [build] Fix CMake system library opt-ins
+
+I'm working on setting up an AUR package for wpimath, and that platform
+generally builds against system versions of libraries instead of
+packaging its own. I had to make a few fixes.
+
+-DUSE_VCPKG_EIGEN now only removes include paths for Eigen instead of
+drake as well.
+
+The USE_VCPKG flags were renamed to USE_SYSTEM since they seem general
+enough for that to work (the find_package() commands work the same way
+on Arch). The unofficial-libuv CMake library file only exists on vcpkg,
+so we can either keep it as-is (only works on vcpkg) or provide our own
+library file for finding the system install.
