Well, I want clients of this library to be able to compile it without too many 
tricks. I assume your command changes the path in the cache to a different svn 
client. Is that right?

I found that uninstalling the cygwin svn client, makes things work (cmake then 
finds the tortoise command line client). So I'll just tell my clients that they 
have to uninstall their cygwin svn client if they want to compile this code.

Having two svn command line clients may seem odd anyway..?

Perhaps, having the user setting up svn (giving the path to) in the UI would 
make most sense, since the findcommand fails in this case? Not sure how to do 
that however...

Thanks,
