+# RPATH
+#
+#   The default runtime path (used on Unix systems to search for
+#   dynamically-linked libraries) is set to include the location that
+#   libraries will be installed to (as set in LIB_INSTALL_DIR), and also
+#   the linker search path.
+#
+#   Note that LIB_INSTALL_DIR needs to be set before including this
+#   module.  Typically, this is done by including the KDEInstallDirs
+#   module.

+#   This section can be disabled by setting
+#     KDE_SKIP_RPATH_SETTINGS
+#   to TRUE before including this module.
+#
+#
+# TEST
+#
+#   Testing is enabled by default, and an option (BUILD_TESTING) is
+#   provided for users to control this. See the CTest module
+#   documentation in the CMake manual for more details.

+#   This section can be disabled by setting
+#     KDE_SKIP_TEST_SETTINGS

+# BUILD
+#
+#   Various CMake build defaults are altered, such as searching source
+#   and build directories for includes first and enabling automoc by
+#   default.
