FEniCSx issue with UFCx

General
1

I am trying to install FEniCSx from source on my MAC machine. I followed the instructions on the repository. I installed FFCx following the commands:

$ cmake -B build-dir -S cmake/
$ cmake --build build-dir
$ cmake --install build-dir

This went successfully. However, when I install FEniCSx I recieve this error:

CMake Error at /opt/homebrew/Cellar/cmake/3.30.3/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
  Could NOT find UFCx (missing: UFCX_INCLUDE_DIRS UFCX_VERSION) (Required is
  at least version "0.9")

      Reason given by package: UFCx could not be found.

I see that the file ufcx.h is located in /usr/local/bin. Can you help me resolve this issue?

Thank you.

I noticed that the FFCx that I installed is version 0.8. Perhaps that is the issue?

Please remove the $ ahead of each of the commands above, as it is meant to avoid people copy-pasting and executing at once.
The commands that should be run is

cmake -B build-dir -S cmake/
cmake --build build-dir
cmake --install build-dir

Thank you for the answer. I did not use $ in the command line. The issue is still present.

What is the output of the commands above?

These are the commands and the response (pwd: ffcx):

You need to set the cmake_install_prefix if you insist on only installing UFCx, and not all of ffcx.

I am not sure why you would want to only have the UFCx interface, if you plan to use it with DOLFINx.

I would simply install it through
pip install fenics-ffcx
