Well I think it's something related to the platform, because both on my 
Linux
box and windows it works perfectly.

This is the interesting part anyway:

foreach(egg ${egg_list})
   #TODO: now I need to replace the name with only the last part of the path
   get_filename_component(egg_name ${egg} NAME)
   set(egg_install ${egg_name}_install)
   # generate the list of targets to create more easily dependencies
   list(APPEND egg_install_list ${egg_install})

   add_custom_target(${egg_install}
     COMMAND ${PYTHON_EXECUTABLE} setup.py -q bdist_egg -d 
${EGG_BUILD_DIRECTORY}
     WORKING_DIRECTORY ${egg}
   )

endforeach()

add_custom_target(install_all_eggs
   DEPENDS ${egg_install_list}
)

#TODO: add this target to the dependencies of run and packing if it works
add_custom_target(unzip_all_eggs
   # unzip the eggs and clean up the zips
   COMMAND ${PYTHON_EXECUTABLE} ${UNZIP_SCRIPT} ${EGG_BUILD_DIRECTORY} 
${EGG_UNZIPPED_DIRECTORY}
   # copy the two run files in the final destination
   COMMAND ${CMAKE_COMMAND} -E copy ${EGG_BUILD_DIRECTORY}/${RUNNER} 
${EGG_UNZIPPED_DIRECTORY}/${RUNNER}
   COMMAND ${CMAKE_COMMAND} -E copy ${EGG_BUILD_DIRECTORY}/${C_RUNNER} 
${EGG_UNZIPPED_DIRECTORY}/${C_RUNNER}

   DEPENDS install_all_eggs
)


sdo the targets are generated at cmake-time reading from a file and then 
there are few more targets that depend on
all of them.

Is there anything wrong in this part?
