## waLBerla's main cmake file
##
## Contents:
## - definition of build options
## - compiler variables ( c++ standard, warnings etc. )
## - Finding of service libraries. Required: boost, Optional: MPI, PE, METIS
## the include paths are set, and the libraries are added to variable SERVICE_LIBS
## - Subdirectory cmake lists are called
## -> src/ this folder contains all modules, each module (that contains c or cpp files) is linked to a
## static library. Dependencies between these shared libraries are tracked manually,
## for more information see waLBerlaModuleDependencySystem.cmake
## -> tests/ Same subdirectories as src/ folder. Contains tests for each module
## - Export of variables into internal cache variables, for usage in applications or projects that use walberla as
## subdirectory. Variables containing the service-libs,
