CMake: Iterate over multiple source files for multiple executables

edit

Hi,

I am trying to minimize the size of my CMakeLists.txt file by iterating over my source files and using a foreach() to add my executables (each of my source files is a seperate executable). I did something similar to this stackoverflow question and other variants but I just cant get my packages to compile. I have tried using set() and file(RELATIVE ...) with and without wildcards (*.cpp) but it still doesn't work. When using the method similar to the stack overflow question, I get the following compilation error:

make[2]: *** No rule to make target 'frasier/frasier_navigation/frasier_behavior/CMakeFiles//home/piraka9011/catkin_ws/src/frasier/frasier_navigation/frasier_behavior/src/conditions/face_rec_condition.dir/depend'.  Stop.
CMakeFiles/Makefile2:5266: recipe for target 'frasier/frasier_navigation/frasier_behavior/CMakeFiles/home/piraka9011/catkin_ws/src/frasier/frasier_navigation/frasier_behavior/src/conditions/face_rec_condition.dir/all' failed
make[1]: *** [frasier/frasier_navigation/frasier_behavior/CMakeFiles/home/piraka9011/catkin_ws/src/frasier/frasier_navigation/frasier_behavior/src/conditions/face_rec_condition.dir/all] Error 2

My structure is like this:

catkin_ws/
    src/
        frasier_behavior/
        CMakeLists.txt
        src/
            foo.cpp    
            conditions/
                condition_a.cpp
                condition_b.cpp

Are there any examples of being able to do so or has anyone come across this issue before? Is this even feasible with the ROS package structure?

EDIT: Per gvdhoorn's request, here's what I tried doing (COND_SRCS are my source files for 'conditions' in a behavior tree)

file( GLOB COND_SRCS src/conditions/*.cpp)
foreach( file ${COND_SRCS})
    string( REPLACE ".cpp" "" name ${file})
    add_executable( ${name} ${file})
    target_link_libraries( ${name}  ${catkin_LIBRARIES})
endforeach( file ${COND_SRCS} )

and have tried replace file(GLOB...) with something like

set(COND_SRCS
  src/conditions/face_rec_condition.cpp
  src/conditions/grasp_condition.cpp
  src/conditions/navigation_condition.cpp
)
