+#   * find_package() version matching and the library SOVERSION have no notion
+#     of prerelease ordering.
+#
+# A prerelease label such as "beta.2" therefore lives in ALPS_VERSION_PRERELEASE
+# (see the version block in the top-level CMakeLists.txt), where it affects the
+# display string only -- never the numeric version used for ABI and
+# find_package() decisions.
