When building the example the configure script reports:

-- G4 Examples: AIDA package not found. --> CompositeCalorimeter example disabled
-- G4 Examples: AIDA found. --> gammaray_telescope example with AIDA enabled.

I checked the differences. The gammaray_telescope uses:


set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake ${CMAKE_MODULE_PATH})
find_package(AIDA QUIET)
if(AIDA_FOUND)
  message(STATUS "G4 Examples: AIDA found. --> gammaray_telescope example with AIDA enabled.")~
  add_definitions(-DG4ANALYSIS_USE)~~
else()
  message(STATUS "G4 Example: AIDA not found --> gammaray_telescope example with AIDA disabled.")
endif()


while composite_calorimeter uses just


include(${Geant4_USE_FILE})

if(NOT AIDA_FOUND)
  message(STATUS "G4 Examples: AIDA package not found. --> CompositeCalorimeter example disabled")
  return()
else()
  add_definitions(-DG4ANALYSIS_USE)
endif()


Which probably explains the difference.
