Subject: [CMake] Don't install c++abi headers in standalone libc++ build
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9d1bcc2a8887d3965d8b071eceb88f0f2eab53a2;p=platform%2Fupstream%2Fllvm.git

[CMake] Don't install c++abi headers in standalone libc++ build

This is a refinement on r337833. Previously we were installing two
copies of c++abi headers in libc++ build directory, one in
include/c++build and another one in include/c++/v1. However, the
second copy is unnecessary when building libc++ standalone.
