+# GNUInstallDirs_get_absolute_install_dir(absvar var)
+#
+# Set the given variable ``absvar`` to the absolute path contained
+# within the variable ``var``. This is to allow the computation of an
+# absolute path, accounting for all the special cases documented
+# above. While this macro is used to compute the various
+# ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
+# allow users who create additional path variables to also compute
+# absolute paths where necessary, using the same logic.
