+# - pre-configured paths for CMake
+#
+# Usage:
+#   configure_paths(<PREFIX>)
+#
+# Checks if configure-like prefix and installation paths were passed by the user
+# and sets up corresponding variables for use in install() commands and to fill
+# out .pc files:
+#
+#   PREFIX_PREFIX       defaults to ...     CMAKE_INSTALL_PREFIX
+#   PREFIX_EPREFIX                          PREFIX_PREFIX
+#   PREFIX_SBINDIR                          PREFIX_EPREFIX/sbin
