Of course I read the documentation. Alas after trying various settings
described there in, nothing worked. my settings are ignored and erased.
why did they MPI_C_LIBRARIES and MPI_C_INCLUDE_DIRS/PATH get changed
from cache variables to not chached variables? that seems to be the
cause of the issue. Now how does one override the detection and tell it
what to use in the new module?

Hi Burlen,
_LIBRARIES and _INCLUDE_DIRS are non-cached output variables. The new
functionality should be documented as to how to guide the current
FindMPI:
https://cmake.org/cmake/help/v3.12/module/FindMPI.html#variables-for-locating-mpi
. That being said, is it incorrectl6y detecting or determine the MPI
installation? If that's the case then we should probably fix that
issue instead.

Hi,
I'm trying to transition from cmake 3.8.2 to cmake 3.11.4. There
are a
number of changes the way FindMPI.cmake behaves in 3.11 that are
making
this difficult.
In 3.11 how do I override the settings? For instance I want to set
MPI_C_LIBRARIES, MPI_C_INCLUDE_DIRS? In 3.8 all I had to do was set
those variables myself, before find_package(MPI), and my setting were
used. in 3.11 find_package(MPI) ignores, and wipes out my
settings, and
then fails.
Isn't it a defacto standard of cmake to be able to override find
modules
by setting the libraries and include dirs before the module runs?
