[CMake] Version embedding - how to cause a command when make is run?

[Juan Sanchez]

How about:

 svn info file:///home/juans/svn_repository/svnroot/ | grep '^Revision:'
| sed -e 's/^[^0-9]*//'

on the repository.

Or just:

 svn info | grep '^Revision:' | sed -e 's/^[^0-9]*//'

After doing a svn update, the latest revision on the url seems to be
accurate.  Unfortunately the number seems to apply to the whole
repository.  I guess it's a good way to make sure you are up to date.

"svnlook youngest" seems to do something, but it appears to only work on
the same filesystem as the repository.


Regards,

Juan
