Remove the previous three LINK_COMPONENTS lines. LINK_COMPONENTS is for
names of LLVM components (roughly equivalent to libraries) that should
be linked to your project. It is equivalent to the names you put after
--libs on your invocation of llvm-config below.

> LINK_COMPONENTS += core
> LINK_COMPONENTS += engine

you can fuse the previous two lines on a single one:

LINK_COMPONENTS += core engine
