Does petsc 3.17.5 version compatible with libmesh 1.6.2?

The PETSc 3.17.x release series was started in March 2022

commit 30c35bf2dfad782abeabcf00da45fe2af1c737cf (tag: v3.17.0)

While libmesh 1.6.2 is from August 2021:

commit e98f7419bd062d4c6b3cc3727899e892915af730 (tag: v1.6.2)

so it predates PETSc 3.17 by several months. Therefore it's definitely
possible they are not compatible. Out of curiosity, where is petscversion.h
actually located in your installation of PETSc, since it is not located in
any of the places listed above? Also, how exactly do you install PETSc? If
you follow the directions that are printed to the screen when building
PETSc from source then the PETSc headers should just be located at
$PETSC_DIR/include and $PETSC_ARCH is not needed/used by libmesh configure.
