Linking against the Intel MKL static libraries introduces circular dependencies. Here is a minimal example that fails for me,

# CMakeLists.txt
cmake_minimum_required(VERSION 3.10)
project(test Fortran)
add_executable(main main.f90)
set(LIBRARIES mkl_intel_lp64 mkl_sequential mkl_core)
foreach(_lib ${LIBRARIES})
  add_library(${_lib} UNKNOWN IMPORTED)
  set_target_properties(${_lib} PROPERTIES IMPORTED_LOCATION
    /opt/intel/mkl/lib/intel64/lib${_lib}.a
    IMPORTED_LINK_INTERFACE_MULTIPLICITY 3)
endforeach()
list(APPEND LIBRARIES dl pthread)
target_link_libraries(main PRIVATE ${LIBRARIES})
#target_link_libraries(main PRIVATE ${LIBRARIES} ${LIBRARIES} ${LIBRARIES})
#target_link_libraries(main PRIVATE -Wl,--start-group ${LIBRARIES} -Wl,--end-group)

# main.f90
  call zpotrf
end program

The build fails with undefined references. If I uncomment either of the two last lines in CMakeLists.txt the build succeeds.

Did I misunderstand how IMPORTED_LINK_INTERFACE_MULTIPLICITY works? I thought it works more or less exactly like the commented lines in my CMakeLists.txt example, except in a more elegant way.
