Subject: [libc++] Use PRIVATE to link benchmark dependencies
X-Git-Tag: llvmorg-11-init~7215
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=534c86d172528d791738c0503948ee9bf883a9f3;p=platform%2Fupstream%2Fllvm.git

[libc++] Use PRIVATE to link benchmark dependencies

It's better style to use PRIVATE when linking libraries to executables,
and it doesn't make a difference since executables don't need to propagate
their link-time dependencies anyway.
