That is what install(CODE ...) will do for you.  It will inject your 
code into those files and the code will stay there.  I was not 
suggesting you edit those files directly, just that you could use 
install(CODE, and look at those files to make sure it is doing what you 
want.

To change the file command you would have to change the C++ of CMake. 
If you get install(CODE to work then it will work with any version of 
CMake.  If you can get your code to run just before the file(INSTALL 
then you should be good.
