[CMake] Can't unset suffix

[Wade Williams]

Very sage advice Alan.

When I created a "Hello World" project, I got errors on the quotes  
around "Hello World" from the compiler.

After further experimentation, I found that the default keyboard  
layout on Ubuntu was inserting an invisible character, and that was  
the reason the visible quotes were showing up as a suffix.  Once I  
switched to the regular US layout, it worked as expected.

Thanks,

Wade
