I'll take a look at the 'official' llvm web pages tonight

Up to now I've been using


cmake -G "Unix Makefiles" ../llvm -DCMAKE_INSTALL_PREFIX=~/tools/clang 
-DCMAKE_BUILD_TYPE=Release 
-DLLVM_ENABLE_PROJECTS="clang;libcxx;libcxxabi;libunwind;compiler-rt;lldb;openmp;pstl"


(just added libunwind)


which gives


/home/paulf/scratch/clang/llvm-project/compiler-rt/lib/sanitizer_common/sanitize
r_unwind_linux_libcdep.cpp:26:10: fatal error: 'unwind.h' file not found
#include <unwind.h>
         ^~~~~~~~~~
