I see you’re using lld-link, so we’re talking about Windows here.

Have you gotten it working with the Microsoft linker? Because if so, just replace link.exe with lld-link.exe and it will work.

If you want to bootstrap clang and lld using itself, then you should pass -DCMAKE\_C\_COMPILER=path/to/clang-cl.exe -DCMAKE\_CXX\_COMPILER=path/to/clang-cl.exe -DCMAKE\_LINKER=path/to/lld-link.exe.

Note the clang-cl.exe. \*\*\*Not\*\*\* clang.exe or clang++.exe.

If you do not have specific reason to want to use llvm lld try to use your system provided c++ linker.

Bootstrapping the llvm c++ c++abi can be troublesome on Unix like platforms and I have no experience doing anything like that on windows.

If you already have a c++ toochain and still want to attempt this then you'll need to svn checkout or git clone a version of the llvm toolchain and build it with your native toolchain then switch to using clang and lld.

if you do not have a native c++ toolchain; let's cross that bridge only if you need to.

A complete LLVM toolchain includes
llvm
clang
