Perhaps, you might check how the offending library makes it into the
CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES variables. IIRC, these libraries
are determined by building a small test program and analyzing the link
command line, so linking against the cilkrts library should basically
work if it appears among the implicit link libraries. The results of
the analysis are reported in CMakeFiles/CMakeOutput.log; could you
post it, or the relevant part thereof, for further investigation?
