# cmake docs:
# SOVERSION: What version number is this target.
# For shared libraries VERSION and SOVERSION can be used to specify the
# build version and API version respectively. When building or installing
# appropriate symlinks are created if the platform supports symlinks and
# the linker supports so-names. If only one of both is specified the
# missing is assumed to have the same version number.
#
# For executables VERSION can be used to specify the build version.
# SOVERSION is ignored if NO_SONAME property is set. For shared libraries
# and executables on Windows the VERSION attribute is parsed to extract
# a "major.minor" version number. These numbers are used as the
# image version of the binary.
# cmake usage:
# SET_TARGET_PROPERTIES(pocl PROPERTIES SOVERSION 1.6.3 VERSION 4) ...
# The libtool library version string to use (passed to -version-info).
# See: http://www.nondot.org/sabre/Mirrored/libtool-2.1a/libtool_6.html
# libpocl.so should get only API additions as we are implementing a standard.
#
# The library version encodings into the library file name are platform
# dependent. Therefore we need to be a bit verbose here for the pocl.icd file
# creation to succeed (see Makefile.am).
# Chiefly, GNU differs from BSD, and others are untested. See e.g.
# http://en.opensuse.org/openSUSE%3aShared_library_packaging_policy#Versioning_schemes
