Subject: Use LIST_SEPARATOR rather than escaping in ExternalProject_Add
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1f34379965c1cf104921da5a6cbe7e983c7091ef;p=platform%2Fupstream%2Fllvm.git

Use LIST_SEPARATOR rather than escaping in ExternalProject_Add

Escaping ; in list arguments passed to ExternalProject_Add doesn't seem
to be working in newer versions of CMake (see
https://public.kitware.com/Bug/view.php?id=16137 for more details). Use
a custom LIST_SEPARATOR instead which is the officially supported way.
