Weird.  It worked for me.  Note that, if you're doing an out-of-tree build, you need to do a "make install" in your main build.  Then, in your out-of-tree build, you need to reference the directories from the "install" rather than the "build" directories.  Here's the cmake command I used for my out-of-tree build:

  cmake \
    -G Ninja \
    -DCMAKE_BUILD_TYPE=Release \
    -DLLVM_EXTERNAL_LIT=/local/home/psteinfeld/main/clean/build/bin/llvm-lit \
    -DLLVM_LIT_ARGS=-v \
    -DFLANG_ENABLE_WERROR=On \
    -DCMAKE_C_COMPILER=/home/sw/thirdparty/gcc/gcc-9.3.0/linux86-64/bin/gcc \
    -DCMAKE_CXX_COMPILER=/home/sw/thirdparty/gcc/gcc-9.3.0/linux86-64/bin/g++ \
    -DCMAKE_CXX_STANDARD=17 \
    -DLLVM_TARGETS_TO_BUILD=host \
    -DLLVM_ENABLE_ZLIB=OFF \
    -DLLVM_ENABLE_ASSERTIONS=ON \
    -DCMAKE_CXX_LINK_FLAGS="-Wl,-rpath,$LD_LIBRARY_PATH" \
    -DLLVM_MAIN_SRC_DIR=/local/home/psteinfeld/main/clean/llvm \
    -DCLANG_DIR=/local/home/psteinfeld/main/clean/install/lib/cmake/clang \
    -DLLVM_DIR=/local/home/psteinfeld/main/clean/install/lib/cmake/llvm \
    -DMLIR_DIR=/local/home/psteinfeld/main/clean/install/lib/cmake/mlir \
    ..
