Trouble building the project

[smanilov]

Hello, I watched the presentation "An introduction to Torch-MLIR" at FOSDEM'25 and decided to give it a try.

I made a good effort, including building MLIR itself from source, since mlir-tblgen does not seem to be packaged by the Linux distros that I'm familiar with.

Still, cmake fails to complete successfully, with a bunch of similar looking errors.

Pasting the first one here:

CMake Error at /root/torch-mlir/externals/llvm-project/mlir/cmake/modules/AddMLIR.cmake:214 (a
dd_dependencies):                                                                               Cannot add target-level dependencies to non-existent target "mlir-doc".                     
                                                                                              
  The add_dependencies works for top-level logical targets created by the                     
  add_executable, add_library, or add_custom_target commands.  If you want to                 
  add file-level dependencies see the DEPENDS option of the add_custom_target                 
  and add_custom_command commands.

Are there extra steps needed, when building in a fresh up-to-date instance of Ubuntu?
