Thanks, it has worked indeed, however now I'm experiencing the
following problem, running "make Experimental" yields this:

================================
kurluka ~/foo/build$ make Experimental
   Site: kurluka
   Build name: Linux-c++
Create new tag: 20090304-0728 - Experimental
Start processing tests
Configure project
   Each . represents 1024 bytes of output
    .. Size of output: 1K
Build project
   Each symbol represents 1024 bytes of output.
   '!' represents an error and '*' a warning.

   Uploaded: /home/../foo/build/Testing/20090304-0728/Test.xml
   Submission successful
Built target Experimental
================================

Basically it says, "No tests were found!!!" while CTestTestfile.cmake contains:

=================================
ADD_TEST(FooUnitTests "/home/.../foo/tests/unit/run")
SUBDIRS(boost_lib)
...
SUBDIRS(src)
SUBDIRS(unittest_lib)
==================================

What can be wrong again?

I also don't quite understand how CTest works, am I right in thinking
CTest just executes the test binary and depending on exit code decides
whether tests passed or not?

Thanks for any help in advance!
