This is because the examples doesn't list the dependency manager as a
dependency. I guess I missed that one.
Simply updating the "celix_subproject" to include the dependency_manager as
a dependency (DEPS) should be enough.

The website is out-of-date with these changes. I'll try to get some time
and update it tomorrow.
To build and run the examples:
Run "make deploy"
This takes care of building the libraries/bundles, as well as copying the
bundles to a deploy target (the "deploy" macro used in eg target.cmake in
the examples directory).

The targets are deployed in the directory in which the deploy macro is
used, so for the examples this is in the "{build}/examples/deploy/{target}".
In the target directory there is a "bundles" directory, a
"config.properties" and a "run.sh" script.
Simple running the script (sh run.sh) should be enough to start the
example. Most targets have the shell deployed by default.

The following shell commands are available:
- start/stop/update
- install/uninstall
- ps and inspect

The command names are taken from the Felix Shell (old style), but not all
are implemented completely (eg the inspect command only support "inspect
service capability" with an optional bundle id).

I really dislike CTest's behaviour of only having the possibility of one
test in an executable (better said, one result).
Also since CTest is only a wrapper to starting test, and not a test
framework like CUnit etc, there is still a need for additional libraries
with assertions etc. Since CUnit etc all support test-suites (multiple test
results in one executable), I prefer those over CTest.
Another problem with CTest is reporting. With CTest it is only possible to
create some reports using the VTK "Dashboard". Using some other library
which supports the JUnit XML export makes it easier to integrate the build
with Jenkins/Hudson and other CI tools.

Thanks, I'm really interested to hear if you get them working. Deployment
currently isn't enough for testing Remote Services.
In the deploy directory there has to be a "rs_bundles" directory containing
the endpoints. Currently the deploy macro doesn't support deploying
additional files.
