[Cmake] Trouble with string match

[William A. Hoffman]

CMake does not have the same regular expression parser as perl or tcl, and
\d is not supported.  There is documentation for the regular expression
can be found here:

I think what you want is [0-9], I assume \d is supposed to be a short hand
for decimal numbers.
