# The YADE has the following parameters to configure:
#  INSTALL_PREFIX: path, where Yade will be installed (/usr/local by default)
#  LIBRARY_OUTPUT_PATH: path to install libraries (lib by default)
#  DEBUG: compile in debug-mode (OFF by default)
#  CMAKE_VERBOSE_MAKEFILE: output additional information during compiling (OFF by default)
#  SUFFIX: suffix, added after binary-names (version number by default)
#  NOSUFFIX: do not add a suffix after binary-name (OFF by default)
#  YADE_VERSION: explicitely set version number (is defined from git-directory by default)
#  ENABLE_GUI: enable GUI option (ON by default)
#  ENABLE_CGAL: enable CGAL option (ON by default)
#  ENABLE_VTK: enable VTK-export option (ON by default)
#  ENABLE_OPENMP: enable OpenMP-parallelizing option (ON by default)
#  ENABLE_GTS: enable GTS-option (ON by default)
#  ENABLE_GL2PS: enable GL2PS-option (ON by default)
#  ENABLE_LINSOLV: enable LINSOLV-option (ON by default)
#  ENABLE_PFVFLOW: enable PFVFLOW-option, FlowEngine (ON by default)
#  ENABLE_LBMFLOW: enable LBMFLOW-option, LBM_ENGINE (ON by default)
#  ENABLE_SPH: enable SPH-option, Smoothed Particle Hydrodynamics (OFF by default, experimental)
#  ENABLE_LIQMIGRATION: enable LIQMIGRATION-option, see [Mani2013] for details (OFF by default)
#  ENABLE_MASK_ARBITRARY: enable MASK_ARBITRARY option (OFF by default)
#  runtimePREFIX: used for packaging, when install directory is not the same is runtime directory (/usr/local by default)
#  CHUNKSIZE: set >1, if you want several sources to be compiled at once. Increases compilation speed and RAM-consumption during it (1 by default).
#  VECTORIZE: enables vectorization and alignment in Eigen3 library, experimental (OFF by default)
