#  Alpha Release:
#  Shell script for installing dependencies
#
#  [README]
#  This shell script is for downloading the dependencies of SWMM 5+. The dependencies
#  include:
#  (1) json-fortran, from: https://github.com/jacobwilliams/json-fortran.git
#  (2) SWMM 5 libraries, from: https://github.com/USEPA/Stormwater-Management-Model/archive/v5.1.13.tar.gz
#  (3) OpenCoarray and its dependencies, from: https://github.com/sourceryinstitute/OpenCoarrays
#
#  OpenCoarray is a Fortran Coarray libaray designed for GNC compiler (e.g. gfortran series).
#  Before we start the installation/compile of SWMM5+, we strongly recommand users to check the
#  of compiler version. If user is using Intel Compiler, then the OpenCoarray dependencies
#  installation can be skipped by simply adding a "-t" flag after the command "./build.sh". If
#  user is using gcc compiler, please make sure the compiler version is higher than 6.1.0.
#  The dependencies of OpenCoarray include:
#
#  opencoarrays
#  ├── cmake-3.4.0
#  └── mpich-3.2
#      └── gcc-6.1.0
#          ├── flex-2.6.0
#          │   └── bison-3.0.4
#          │       └── m4-1.4.17
#          ├── gmp
#          ├── mpc
#          └── mpfr
#
#  This script will first check if the above-mentioned pakcages exist in the local directory,
#  If not found -> then download and install.
#  For the OpenCoarray dependencies, script will check the existencce of local copy of cmake and mpich,
#  For the user first time download/compile SWMM5+, all these packages will be downloaded and installed.
#  This is an one-time installation work if user keeps working in the same SWMM5+ directory. However,
#  the dependencies installation process is required everytime after cloning a new version of SWMM 5+.
#
#  More information for the packages can refer to :
#  json fortran : https://github.com/jacobwilliams/json-fortran#brief-description
#  SWMM 5 library: https://www.epa.gov/water-research/storm-water-management-model-swmm
