INSTALL: libsupermesh should be built using the CMake built during PETSc configure

[JDBetteridge]

The installation process frequently fails building libsupermesh because an outdated system CMake is being used.

To work around this issue for PETSc external packages, the installation script will tell PETSc configure to download and build a newer CMake. This should be linked in $VIRTUAL_ENV/bin and used later in the install script to build libsupermesh.

Is there a workaround? I am hitting this problem.

firedrake-install --pip-install cmake Should add a more up to date CMake to your virtualenv at install time.

Alternatively, to pick up a previously failed install:

pip install cmake
firedrake-update

It was

cmake version 3.28.3

after first command got

Successfully installed cmake-3.31.1

then, update works. Testing now...
Thanks!
