If you are using CMake 2.2 or earlier, read the documentation of the 
SET_TARGET_PROPERTIES command.  Use the POST_INSTALL_SCRIPT option.  If 
you're using CMake from CVS then look at the INSTALL command's SCRIPT 
mode.  Inside the CMake script use EXEC_PROGRAM (for 2.2 and earlier) or 
EXECUTE_PROCESS (CVS version) to invoke the command.

In order to avoid creating a separate CMake script you could use the 
FILE command's WRITE mode to write the CMake script from your 
CMakeLists.txt file into the build tree.  It could be packaged up inside 
a macro.
