CMake Error at CMakeLists.txt:12 (FIND_PACKAGE):
  By not providing "FindDOLFIN.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "DOLFIN", but
  CMake did not find one.

  Could not find a package configuration file provided by "DOLFIN" with any
  of the following names:

    DOLFINConfig.cmake
    dolfin-config.cmake

  Add the installation prefix of "DOLFIN" to CMAKE_PREFIX_PATH or set
  "DOLFIN_DIR" to a directory containing one of the above files.  If "DOLFIN"
  provides a separate development package or SDK, be sure it has been
  installed.

It looks like I need to manually install DOLFIN. Is that expected or should it get installed automatically during Pkg.add("FEniCS")?
If the former, any pointers on how to install it on macOS? It looks like it's not available on brew.

Best,
Christophe

Is that related to mshr?

You might want to just install the FEniCS Docker and put Julia on that, and see if that installation process is easier. FEniCS seems to really push their Docker install as "the true install", so maybe we need to just use it.
