[PATCH] D29931: [Cmake] Install the isl headers into the install tree

[Philip Pfaffe via Phabricator via llvm-commits]

Herald added a subscriber: mgorny.

isl headers are currently missing in a Polly installation. Because the Polly headers depend on those, code can't be compiled against an installed Polly.

This patch installs the isl headers. I left a TODO, as optionally it should be possible to use a system version of isl instead of the one shipped with Polly.

When compiling, clients of the installation need to add -I${PREFIX}/include/polly/ to there include path right now, because there currently is no way to export this path automatically.
