# There are 2 layers to the MPI mpif.h layer. The only extra thing
# that determine mpif.h bindings is that fortran can be disabled
# by user. In such cases, we need to not build the target at all.
# One layer generates MPI_<foo> bindings. The other layer
# generates PMPI_<foo> bindings. The following conditions
# determine whether each (or both) these layers are built.
#
# Superceeding clause:
# - Fortran bindings should be enabled, else everything is
# disabled
# 1. MPI_<foo> bindings are needed if:
# - Profiling is not required
# - Profiling is required but weak symbols are not supported
# 2. PMPI_<foo> bindings are needed if profiling is required.
#
# Hence we define 2 conditionals which tell us whether each of
# these layers need to be built or NOT
