Bug#904301: libpetsc-real3.9-dev: Include paths to mpi header missing from petscvariables (and pkgconfig)

[Mikael Öhman]

Package: libpetsc-real3.9-dev
Version: 3.9.3+dfsg1-3
Severity: normal

Dear Maintainer,

   * What led up to the situation?

Building a CMake based code using FindPETSc.cmake (which is made by a petsc
dev), it refused to use the petsc3.9 installation, as it failed to build a
small test code.

After some digging, I found that it was only missing the include path to the
mpi headers.
petsc-dev-3.7.5 included the path -I/usr/lib/x86_64-linux-gnu/openmpi/include,
which is gone from the 3.8 and 3.9 packages.

It's missing from petscvariables, but it's also missing from the pkgconfig
file.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Hacking in -I/usr/lib/x86_64-linux-gnu/openmpi/include into PETSC_CC_INCLUDES
resolved the issues with FindPETSc.cmake.

Best regards, Mikael
