[lldb-dev] Problem of building lldb on Mac

[Jeffrey Tan via lldb-dev]

Hi,

I followed instructions in http://lldb.llvm.org/build.html to build lldb on
Mac.

I opened "*lldb/lldb.xcworkspace*" in Xcode7.3.1, select lldb-tools scheme
and build, I always got build error below. I have tried "brew install
cmake" but the installed cmake version does not match what build script is
looking for.

*Questions:*
Do I suppose to find and download 3.1.2 version of cmake to get this
working? Do I miss anything? Thanks.
