+#This macro creates a libtool .la file for shared libraries or plugins. The first parameter is the target name of the library, the second parameter is the directory where it will be installed to. E.g. for a KDE 3.x module named "kfoo" the usage would be as follows:
+
+#The macro GET_TARGET_PROPERTY_WITH_DEFAULT is helpful to handle properties with default values.
+
+#ADD_LIBRARY(foo SHARED kfoo1.cpp kfoo2.cpp)
+#CREATE_LIBTOOL_FILE(foo /lib/kde3)
