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.
