Comment (by Ionic):

 The initial issue presented here is not (immediately) happening because
 the system `clang` version on 10.9 is too old to support initializer lists
 (which would be weird, since it's roughly based upon `clang` 3.4), but
 because `cmake` supplies `-std=gnu++1y`, which it doesn't understand and
 just silently ignores. Instead of enabling the C++11 mode, it just stays
 in the default C++03 mode, leading to the failure seen here.

 Now... does `cmake` actually need C++14? If not, we could switch to
 something like `-std=gnu++11`.
