[Cmake] Trouble with string match

[John Biddiscombe]

Hi all,

I'm passing a number into a macro and do this
IF("${VERSION}" MATCHES "\\d")
do something,

but if the version is actaully not numeric (ie a tag name from CVS), I want
to do something else. The string match "regex" doesn't seem to work

if I do


IF("${VERSION}" MATCHES "1")
it passes
but
IF("${VERSION}" MATCHES \\d)
with the string "1" passed in, it fails.

Any ideas?

thanks

JB
