[CMake] cvs update through ctest

[Bitter, Ingmar (NIH/CC/DRD) [E]]

Hi,

my projects are setup by cmake with a build directory below the main
project directory:

project/
project/build
project/src

I run cmake and ctest from the build directory because I do not want any
automatically created files in the main project directory.
when running ctest -D Continuous it tells me that the current directory
is not a CVS controlled directory, which is correct. How do I tell ctest
to update the project directory?

Or re-worded, what is the proper setup to do an out of source build and
test?
