Bug#996599: xdmf: reproducible builds: Embeds number and type of processor

The processor type and number of processors is embedded in
/usr/lib/x86_64-linux-gnu/cmake/Xdmf/XdmfConfig.cmake, which cause
reproducibility issues.

  set(XDMF_CMAKE_HOST_SYSTEM_PROCESSOR»   »   "x86_64")
vs.
  set(XDMF_CMAKE_HOST_SYSTEM_PROCESSOR»   »   "i686")

  set(XDMF_CMAKE_SYSTEM_PROCESSOR»»"x86_64")
vs.
  set(XDMF_CMAKE_SYSTEM_PROCESSOR»»"i686")

  set(XDMF_MPIEXEC_MAX_NUMPROCS»  »  "9")
vs.
  set(XDMF_MPIEXEC_MAX_NUMPROCS»  »  "10")

The attached patch to debian/rules fixes this by removing these values
from the XdmfConfig.cmake file.

Without knowing xdmf well, I am NOT sure if it is ok to remove these
values from XdmfConfig.cmake, though in order to use the .cmake file it
would seem best to regenerate it in the environment in which is used
rather than the environment where the package happened to be built.

So it is also unclear if XdmfConfig.cmake actually needs to be included
in the package; a better course of action *might* be to remove the file
entirely.


With this patch applied(or removing XdmfConfig.cmake from the package),
xdmf should (really this time!) become reproducible on
tests.reproducible-builds.org.


Thanks for maintaining xdmf!


live well,
