######################### SCHISM Local Compiler and System Settings
#
#
#   This file contains the local compiler settings and system choices such as MPI_VERSION
#   It is meant to be used as a cache init file with the -C option. 

#   For purposes of clarity and re-usability, the configuration examples have been separated into
#   system locations and compilers (this file) and module/algorithm choices (e.g. USE_SED,TVD_LIM). 
#   An example of the latter is given in SCHISM.build.build.sample

#   I practice, these can be separate (for people who don't like repeating system settings) or 
#   together. In the latter case, cmake works fine with two init files: cmake -C<init1> -C<init2>

# Compiler choice and any unusual flags. 
# Defaults for Intel, GFortran and PGI are provided in SCHISM.Compile.cmake, so technically you do not need to set them
# if you have one of these.  However correct/optimal flags are often very specific to 
# an HPC architecture. This is where you set this type of information

#set(MPI_VERSION CACHE STRING 2 "Version of MPI Interface, which is the default usually 2 but pleiades is 1")
#set(CMAKE_Fortran_FLAGS_RELEASE "-O2 -cpp -assume byterecl CACHE STRING "Fortran flags")
#set(CPREPRO_FLAG -cpp CACHE STRING "Vendor-specific flag to force use of the C Preprocessor")
#set(USE_OPEN64     CACHE BOOLEAN OFF )   #Might be needed if you are using this compiler
set(MPI_VERSION    CACHE STRING  "2")



##########################  LOCATIONS #########################################################
#
# LOCATIONS: Set locations for NetCDF (possibly HDF5 if NetCDF links to it), ParMetis, PETSc
#            You don't need to set these if they are in your environment
#
#            Only the library home location is needed and the /lib or /bin part will be inferred.
#            Generally traditional structure is assumed, but the Parmetis and GOTM libraries
#            that are included have a slightly different structure
#
#            You only need PETSc for WWM
#            You only need GOTM if you intend to use it with USE_GOTM
#            GOTM and ParMetis local copies will be found automatically, but also can overridden
#            You have to build them
#

# This cannot be set by hardwiring, the default pointing to the internal copy should be correct
# set(PARMETIS_DIR  path/to/Parmetis CACHE PATH "Path to ParMetis")
