[petsc-users] petscconf.h missing building cpp file with dolfinx?

[Satish Balay]

We do not recommend installing PETSc in /usr/include [aka --prefix=/usr].  Now you have some petsc includes here that will potentially conflict with any other install of PETSc you might attempt.

You might have to manually check - and delete PETSc installed files from here.

For most uses - one can install PETSc in $HOME

If you need a common install - suggest --prefix=/usr/local/petsc-version

So after .configure mak sudo make install I found there was some type of difficulty with the destination directory so I copied the files manually into usr/includes of Ubuntu 22.04 jammy. So some petsc header files are now found for compiling cpp dolfinx source code but petscconf.h still not found by dolfinxs source tree of header files. Anyone know how to remedy this so dolfinx cpps can find petsscconf.h that g++ is claiming as missing? Thank you!
