Umbrello wants to add the svn version to it's version string

[Michael Jansen]

Hi

With commit 5d5674cbd26deecbb82c76c55581b21957b00508 in kdesdk andi tried to 
add the subversion string to the umbrello version. The current implementation 
has some drawbacks.

  - Only works in svn checkouts (yeah i know)
  - Fails the configuration step everywhere else (git-svn for me, i guess
    released package too (tgz)) if subversion is found.

CMake Error at /usr/share/cmake/Modules/FindSubversion.cmake:83 (MESSAGE):
  Command "/usr/bin/svn info
  /home/mjansen/kde/trunk/src/devel/kdesdk/umbrello/umbrello" failed with
  output:

  svn: '/home/mjansen/kde/trunk/src/devel/kdesdk/umbrello/umbrello' is not a
  working copy

Call Stack (most recent call first):
  umbrello/umbrello/CMakeLists.txt:11 (Subversion_WC_INFO)

Do we have some common flexible solution somewhere?

Since i guess that is/will be a common desire perhaps we can together create a 
solution that works everywhere.

@Andi Please revert you change until we have a common solution. As a short fix 
check for a .svn directory in CMAKE_SOURCE_DIR and only try to execute that 
stuff if found.

My idea would be something like that

ECM_GET_VCS_VERSION( [DIRECTORY source_dir] )

Check in the directory for a .git dir -> git checkout -> try git svn info -> 
try some git log 
Check in the directory for a .svn dir -> try svn whatever
Else: No version
