Correction: to pass a string with *literal* spaces you need quotes:

   set(SOMEPATH "c:/program files/foobar")

When passing a string through a variable you need quotes only if the 
value contains semicolons, so this will work fine for paths:

   set(PATHVAR ${SOMEPATH})

In this case even if SOMEPATH contains semicolons it will be split into 
multiple arguments, passed to the "set" command, and then recomposed by 
the command and stored in PATHVAR as a list with semicolons so the value 
will not change anyway.  For other commands the splitting on semicolons 
may make a difference, such as the "string" command.  In these cases 
double-quoting ensures that the value is passed as a single argument and 
not split.
