No, CMAKE_DL_LIBS is for libdl, the dynamic linker (i.e. "plugin"  
loading). You need to pass the -static-intel flag to the compiler  
during linking. You can to that either using the LINK_FLAGS target  
property (but then make very sure that you're really using an intel  
compiler in you CMakeLists.txt) or set the CMAKE_XXX_LINKER_FLAGS in  
the cache (where XXX is one of EXE, SHARED or MODULE).

This worked for me:

project(test Fortran)

add_executable( test test.f90 )

# test whether this is an intel compiler, then use -static-intel when  
linking
if( CMAKE_Fortran_COMPILER_ID STREQUAL Intel )
   set_target_properties( test PROPERTIES LINK_FLAGS -static-intel )
endif( CMAKE_Fortran_COMPILER_ID STREQUAL Intel )
