#
# Adds optional Fortran support.
# Appends EXTRA_FCFLAGS to CMAKE_Fortran_FLAGS.
# If environment variable FCFLAGS is set, then the FCFLAGS are used
# and no other flags are used or appended.
#
# Variables used::
#
# EXTRA_FCFLAGS
# ENABLE_FC_SUPPORT
#
# Variables defined::
#
# CMAKE_Fortran_MODULE_DIRECTORY (${PROJECT_BINARY_DIR}/include/fortran)
#
# Variables modified::
#
# CMAKE_Fortran_FLAGS
#
# Variables set::
#
# ENABLE_FC_SUPPORT
#
# Environment variables used::
#
# FCFLAGS
#
# Example autocmake.cfg entry::
#
# [fc]
# source: https://github.com/scisoft/autocmake/raw/master/modules/fc.cmake
# docopt: --fc=<FC> Fortran compiler [default: gfortran].
# --extra-fc-flags=<EXTRA_FCFLAGS> Extra Fortran compiler flags [default: ''].
# --fc-support=<FC_SUPPORT> Toggle Fortran language support (ON/OFF) [default: ON].
# export: 'FC=%s' % arguments['--fc']
