I get the errors below from lld when running unit tests. It appears<br>
that clang doesn't know or isn't providing the necessary link paths for<br>
system libraries to lld.<br>
<br>
I haven't be able to find many guides about building clang on OSX. The<br>
ones I have found use Xcode but for various reasons I would rather not<br>
have to do that. Is Xcode the only way to build clang on OSX? If not,<br>
is there a CMake variable or other setting that tells clang or lld where<br>
the system libraries are?<br>
<br>
Thanks for any help!<br>
