Note that the example experiment compiles a simple example frontend and a root-based analyzer. If you don't have 
ROOT installed, you of course cannot compile the analyzer. If you don't need the analyzer, remove it from the 
Makefile/CMakeLists.txt

It's not clear to me why the frontend did not compile on our server machine. You did not post the command how you 
initiated the build. Note that there are now two parallel build schemes: the traditional Makefile and the new 
CMakeFiles.txt. We try to maintain both of them, so you have to specify which one you use when you get an error.

I realize now that the CMakeLists.txt in the experiment example directory builds nicely under midas, but when you move 
it to another directory and extract it from the normal build scheme it breaks. I rewrote the CMakeLists.txt now that it 
looks for MIDASSYS and also build at different locations. Do

cd $HOME/online
cp $MIDASSYS/examples/experiment/* .
mkdir build
cd build
cmake ..
make

and it should work. Of course first pull the current develop version.
