[CMake] setting a list using the -D option

[Darby J Van Uitert]

Hello,

How do I set the value of a list using the -D option when running cmake? 
For example, if I want FOO to be a list containing the letters a, b, and 
c, I thought I would do something like
 >cmake ../src -DFOO:STRING="a b c"
I tried this but then it just treats it as a string and my foreach loop 
only runs once. Any input is appreciated.
