Thanks for working on this!

But I couldn't get it working for me.  Here's what I tried.

I started with an existing full build that includes llvm and mlir.  The full path of this build is /local/home/psteinfeld/master/b4/build/.  I have a script that does an out-of tree build based on this full build.  Here's the script:

  #!/bin/bash
  cmake -G Ninja \
    -DFLANG_ENABLE_WERROR=On \
    -D LLVM_DIR=/local/home/psteinfeld/master/b4/build/lib/cmake/llvm \
    -D MLIR_DIR=/local/home/psteinfeld/master/b4/build/lib/cmake/mlir \
    -DCMAKE_BUILD_TYPE=Release ..

I then created a script that uses relative paths.  Here's the contents of my new script:

  #!/bin/bash
  cmake -G Ninja \
    -DFLANG_ENABLE_WERROR=On \
    -D LLVM_DIR=../../../b4/build/lib/cmake/llvm \
    -D MLIR_DIR=../../../b4/build/lib/cmake/mlir \
    -DCMAKE_BUILD_TYPE=Release ..

I then downloaded the source into the directory /local/home/psteinfeld/master/diana/.  I then "cd"ed to the "flang" directory and created a directory called "build" and did a "cd build".  At this point, doing "pwd" yields "/local/home/psteinfeld/master/diana/flang/build".  I then ran my new script.  Running it produced the following errors:

...

- Performing Test C_SUPPORTS_FDATA_SECTIONS
- Performing Test C_SUPPORTS_FDATA_SECTIONS - Success
- Performing Test CXX_SUPPORTS_FDATA_SECTIONS
- Performing Test CXX_SUPPORTS_FDATA_SECTIONS - Success

CMake Error at CMakeLists.txt:81 (find_package):

  Could not find a package configuration file provided by "MLIR" with any of
  the following names:
  
    MLIRConfig.cmake
    mlir-config.cmake
  
  Add the installation prefix of "MLIR" to CMAKE_PREFIX_PATH or set
  "MLIR_DIR" to a directory containing one of the above files.  If "MLIR"
  provides a separate development package or SDK, be sure it has been
  installed.

- Configuring incomplete, errors occurred!
