+# Note: pass only standard cmake macros here.
+# The only exception is SYSCONF_INSTALL_DIR, used commonly in KDE packages,
+# where the default (${CMAKE_INSTALL_PREFIX}/etc) is not FHS-compliant and
+# absolute path MUST be used to comply with FHS.
+# The other non-standard cmake macros used commonly in KDE
+# (INCLUDE_INSTALL_DIR, LIB_INSTALL_DIR, SHARE_INSTALL_PREFIX)
+# have sane default values in KDE, and some packages use these names
+# in different way (e.g. expect them to be always relative or always
+# absolute).
