[CMake] ifort,icc,icpc: ld: cannot find -lcilkrts

[Ilias Miroslav]

Dear experts,

our problem is that cmake sets automatically linking libraries for C,C++ and with Intel compilers (Fortran,C,C++) we are getting these problems
( first observed here https://repo.ctcc.no/CDash/viewBuildError.php?buildid=5283 ) :
.
.
.
Linking Fortran executable dirac.x
/people/disk2/ilias/bin/cmake_install/bin/cmake -E cmake_link_script CMakeFiles/dirac.x.dir/link.txt --verbose=1
/people/disk2/magnus/intel/composerxe-2011.2.137/bin/intel64/ifort    -static -Wl,-E -w -assume byterecl -DVAR_IFORT -g -traceback -static-libgcc -static-intel -i8 -O0 CMakeFiles/dirac.x.dir/main/main.F90.o  -o dirac.x -i_dynamic lib/libdirac.a lib/libxcfun.a -ldecimal -lcilkrts -lstdc++ -lirc 
ld: cannot find -lcilkrts
make[3]: *** [dirac.x] Error 1
.

Manual linking without the "-lcilkrts" flag works:

ilias at fe6.dcsc.sdu.dk:~/QCH_Work/qch_progs/dirac_git/trunk/build_ompi_ifort_icc_ilp64_static/.

The problematic "cilkrts" library is set automatically within CMAKE_C_IMPLICIT_LINK_LIBRARIES & CMAKE_CXX_IMPLICIT_LINK_LIBRARIES variables, as found:

ilias at fe6.dcsc.sdu.dk:~/QCH_Work/qch_progs/dirac_git/trunk/build_ompi_ifort_icc_ilp64_static/.grep cilkrts *  */*
.
CMakeFiles/CMakeCCompiler.cmake:SET(CMAKE_C_IMPLICIT_LINK_LIBRARIES "imf;svml;m;ipgo;decimal;cilkrts;stdc++;irc;c;irc_s;dl;c")
CMakeFiles/CMakeCXXCompiler.cmake:SET(CMAKE_CXX_IMPLICIT_LINK_LIBRARIES "imf;svml;m;ipgo;decimal;cilkrts;stdc++;irc;c;irc_s;dl;c")
.
.

Please how to remove  "cilkrts" or any other parameter from CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES, 
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_LANG_IMPLICIT_LINK_LIBRARIES  ?

We have cmake version 2.8.4 and  Intel is Intel(R) 64, Version 12.0.2.137 Build 20110112.

Yours, M.Ilias
