You should change it to do:
EXECUTE_PROCESS( COMMAND rm -rf  /* RESULT_VARIABLE ret_var)

:-)

Only kidding....

The problem is that you are running rm without a shell.   The shell is 
the one that
expands the */*.~ stuff and passes the expanded list to rm.   So, this 
might work:

EXECUTE_PROCESS( COMMAND sh rm -vf  */*.*~ RESULT_VARIABLE ret_var)

To be more portable, you should look at the FILE command.
Specifically these two options:

 FILE(GLOB_RECURSE variable [RELATIVE path])
 FILE(REMOVE [file1 ...])
