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.

you can fuse the previous two lines on a single one:
LINK_COMPONENTS += core engine
