# SONAME, SOVERSION
#
# The rule is that each new release or bug fix release should increse the soversion.
#
# SOVERSION is $(SONAME_VERSION).$(SOVERSION_MINOR).$(SOVERSION_RELEASE)
#
# - If the binary interface of libraries do not change from previous release
# (example: most bug fix releases), increase SOVERSION_RELEASE (this third number).
# - If the binary interface is changed, but remains compatible with
# previous release (example: only addition of new functions), then increase
# SOVERSION_MINOR (second number) and set SOVERSION_RELEASE to 0.
# - If the binary interface is changed in an incompatible way to previous
# release, then increase the SONAME_VERSION, and set the two other
# numbers to 0.
#
# SOVERSION history:
# CGAL<=3.5 : (unversionned)
# CGAL-3.5 : 4.0.0
# CGAL-3.5.1 : 4.0.1
# CGAL-3.6 : 5.0.0

# std::size_t, which is different on some platforms)
# CGAL-3.8 : 7.0.0 (At least CGAL::Random has changed its member fields.)
