# FindPNETCDF

# -----------
|
|
#
|
|
# Find parallel IO library for classic netCDF files
|
|
#
|
|
# This module will define the following variables:
|
|
#
|
|
# ::
|
|
#
|
|
# PNETCDF_FOUND
|
|
# PNETCDF_INCLUDE_DIRS
|
|
# PNETCDF_LIBRARIES
|
|
# PNETCDF_VERSION
|
|
# PNETCDF_ERANGE_FILL - True if PnetCDF was built with ``NC_ERANGE`` support`
|
|
# PNETCDF_HAS_RELAXED_COORD_BOUND - True if PnetCDF was built with relaxed coordinate bounds
|
|
#
|
|
# The ``PNETCDF::pnetcdf`` target will also be exported
