Subject: cmake: create a relative symlink to clang, not absolute
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3d9000dc90485d5a3f254f4b65d8f5a675ab0594;p=clang

cmake: create a relative symlink to clang, not absolute

Hardcoding the location of the build directory seems like it would
break at `make install`/packaging time.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150201 91177308-0d34-0410-b5e6-96231b3b80d8
