I also struggled with getting a SVN revision into my source code.
By the looks of this my solution can be improved :-)

This is verry unix like solution. I used a Python script with the PySvn
plug-in. For me it works on both XP and Linux.
First I tried a CMake macro as in:
ADD_CUSTOM_TARGET(OutputSvnVersion ALL
${MY_SVN_MACRO})
Which obviously doesn't work. It should be a nice feature to have, in my
opinion. That way there is no/less need for using external scripts.
Anyway: Could CMake provide some standard macro's to generate such files on
build time? It seems to me that a lot of people would benefit from it. I mean
this isn't the first post on the subject, is it?
Kind regards,
Sander.
