I mean that I can build all the targets in command line without problem and execute them without any problems.

Here it is:

#*****************************************************************************************

find_package(MKL)

set(HAVE_INTEL_MKL ${MKL_FOUND})
if (MKL_FOUND)
    include_directories(${MKL_INCLUDE_DIRS})
    link_directories(${MKL_LIBRARY_DIRS})
endif()

# [snip]

sfo_executable(benchmark test/benchmark.cc)
target_link_libraries(benchmark submodularity xxx_func_fw qr_updates)
if (UNIX)
  find_library(RT_LIBRARY rt)
  if(RT_LIBRARY)
    target_link_libraries(benchmark ${RT_LIBRARY})
  endif()
endif()

#*****************************************************************************************

Thank you.
Best regards,
Giovanni
