GEOS-ESM CMake Configuration Files

This repository contains many of the CMake settings, macros, and functions used for the GEOSgcm and other GEOS-ESM projects.

Main Directory

The main directory contains two files: esma.cmake and esma_cpack.cmake.

The esma.cmake file is the "omnibus" script which loads most of the other functions and macros used by GEOS-ESM. A good portion of it sources other .cmake files contained in the subdirectories listed below via use of appending to CMAKE_MODULE_PATH.

The esma_cpack.cmake file controls the use of CPack within GEOS-ESM. Due to interactions between GEOS-ESM's cmake and ecbuild's, this file must be included separately

Subdirectories

The rest of the GEOS-ESM CMake configuration files are contained in subdirectories:

• esma_support

  Macros and functions used to simplify and extend CMake or ecbuild (see below) capabilities. This includes things like esma_add_library() and other esma_ macros that might be encountered in GEOS-ESM CMake.

• compiler

  Files related to different compiler options as well as some CMake-time checks for compiler support.

• operating_system

  Files related to OS-specific configurations

• python

  Files related to the detection and use of Python during the build process. For GEOS-ESM projects, this nearly always means f2py.

• latex

  Files related to LaTeX processing.

• external_libraries

  Files that control the detection and use of external libraries and other dependencies. This includes things like Baselibs (netCDF, ESMF, etc.), math libraries (MKL, BLAS, LAPACK), as well as Git.

• ecbuild

  There is a final "hidden" subdirectory that ESMA_cmake expects. This is a checkout of ecbuild which is an underlying framework for most of ESMA_cmake. This is brought in as a subdirectory via mepo from components.yaml files in fixtures.
