# G4CMP/GNUmakefile	Top-level driver to build library and demos
# $Id: b50f1e17e36e73b8ee4a2e6a8e10327f3864cbbd $
#
# Add Mac and Windows handling for Qhull build (we aren't using CMake there)
# Add "dist" target to make tar-ball for distribution to non-SLAC users
# Temporarily exclude "channeling" from all examples, until it builds
# Add G4CMP_SET_ELECTRON_MASS support to build with dynamic mass code
# Move individual examples to "examples/" directory, add tools and tests
# Move QHull down to library/ directory; update tar-ball generator
# Drop G4CMP_SET_ELECTRON_MASS code blocks; not physical
# Add new "sensors" example directory
# Add top-level ".g4cmp-version" file to track as-built tag/SHA
# Add Geant4 version checking
# Manually set version with G4CMP_VERSION=xxx if Git not available
# Add pass-through of thread-safety "code sanitizer" flags
# Split XXX.% targets to ensure everything gets built properly

# G4CMP requires Geant4 10.4 or later
g4min := 10.4
