# - Try to find PETSc
# Once done this will define
#
# PETSC_FOUND - system has PETSc
# PETSC_INCLUDES - the PETSc include directories
# PETSC_LIBRARIES - Link these to use PETSc
# PETSC_COMPILER - Compiler used by PETSc, helpful to find a compatible MPI
# PETSC_DEFINITIONS - Compiler switches for using PETSc
# PETSC_MPIEXEC - Executable for running MPI programs
# PETSC_VERSION - Version string (MAJOR.MINOR.SUBMINOR)
#
# Usage:
# find_package(PETSc COMPONENTS CXX) - required if build --with-clanguage=C++ --with-c-support=0
# find_package(PETSc COMPONENTS C) - standard behavior of checking build using a C compiler
# find_package(PETSc) - same as above
#
# Setting these changes the behavior of the search
# PETSC_DIR - directory in which PETSc resides
# PETSC_ARCH - build architecture
#
