[CMake] File names with unbalanced square brackets

[Petr Kmoch]

Hi Allen.

I'm not sure whether it's documented, but CMake interprets square brackets
as escaping the semi-colon character (which means a semi-colon in square
brackets will not work as a list item separator). You will probably have to
translate the file names for CMake processing by replacing [ and ] with a
different string, and replacing it back just before use outside of CMake.
