UPDATE minimal working example
I have created a minimal working example in a public svn repo. Checkout the proj folder from trunk, it has a CMakeLists.txt and main.cpp (code below posted). In the trunk I also have the lib folder, which is the static library implementing a class. This class is used in my main. I'm behind a proxy, so I have in the ~/.subversion/server added the global proxy setup.
Expected behavior: After checkout of proj do cmake . which also does a checkout lib and executes a make to create libmylib.a prior to build my main. Finally make my main project.
Actual behavior: Does not checkout lib so libmylib.a is not built. Error message:

Original post
I have a ROS package (pomdp_planner) linked with a Makefiel project (project_appl). I have both projects on our SVN but different locations (I'm behind a proxy). If I have a fresh checkout of the ROS node and build it, it fails to download the Makefile project, so building fails at linking phase. In case I manually checkout the Makefile project at the desired location then the ROS PKG is built
My issue is that the Makefile project in the externalproject_add() is not updated to the current version on SVN and it isn't even checked out at the beginning. To build the ROS pkg I use catkin_tools.
I working on Ubuntu 14.04, cmake 2.8.12.2 (and ROS Indigo).
My ROS pkg CMakeList:
