+#--------------------------------------------------------------------
+#	The statements below define a collection of symbols related to
+#	dynamic loading and shared libraries:
+#
+#	CMAKE_SHLIB_CFLAGS -	Flags to pass to cc when compiling the components
+#			of a shared library (may request position-independent
+#			code, among other things).
+#	CMAKE_SHLIB_LD_LIBS -	Dependent libraries for the linker to scan when
+#			creating shared libraries.  This symbol typically
+#			goes at the end of the "ld" commands that build
+#			shared libraries. The value of the symbol if
+#			"${LIBS}" if all of the dependent libraries should
+#			be specified when creating a shared library.  If
+#			dependent libraries should not be specified (as on
+#			SunOS 4.x, where they cause the link to fail, or in
+#			general if Tcl and Tk aren't themselves shared
+#			libraries), then this symbol has an empty string
+#			as its value.
+#	CMAKE_SHLIB_SUFFIX -	Suffix to use for the name of the shared library.  An
+#			empty string means we don't know how to use shared
+#			libraries on this platform.
+#	CMAKE_SHLIB_BUILD_FLAGS -
+#                       Flags to use when building a shared library.	
+#	CMAKE_SHLIB_LINK_FLAGS -	
+#                       Flags to pass to the compiler when linking object
+#			files into an executable application binary such
+#			as tclsh.
+#--------------------------------------------------------------------
+
+
+# Step 2: check for existence of -ldl library.  This is needed because
+# Linux can use either -ldl or -ldld for dynamic loading.
+
