Unexpected configuration

[floli]

Hello,
cmake tells me

-- petsc_lib_dir /home/florian/software/petsc/arch-linux2-c-debug/lib
-- Recognized PETSc install with single library for all packages
-- Performing Test MULTIPASS_TEST_1_petsc_works_minimal
-- Performing Test MULTIPASS_TEST_1_petsc_works_minimal - Failed
-- Performing Test MULTIPASS_TEST_2_petsc_works_allincludes
-- Performing Test MULTIPASS_TEST_2_petsc_works_allincludes - Success
-- PETSc requires extra include paths, but links correctly with only interface libraries.  This is an unexpected configuration (but it seems to work fine).
-- Found PETSc: /home/florian/software/petsc/include;/home/florian/software/petsc/arch-linux2-c-debug/include;/opt/mpich/include (found suitable version "3.8.4", minimum required is "3.6")

I use it like

find_package(PETSc 3.6 REQUIRED)
include_directories(${PETSC_INCLUDES})

add_library(mylib ${sourcesAllNoMain})
target_link_libraries(mylib PUBLIC ${PETSC_LIBRARIES})

Is there something I should or can do about that? I compiled petsc from source using the git maint branch.

Best Thanks!

This sometimes occurs when you use compilers that don't know about MPI or you use mismatched MPI compilers. So just check that.
