[CMake] One more simple question

[Carminati Federico]

Dear All,
  thanks to everybody for the support I got so far. I have now another simple question. The CMAKE FAQ gives a good recipe on how to use a different compiler

http://www.cmake.org/Wiki/CMake_FAQ#Method_2:_use_cmake_-D

however I do not know how to use a different linker other than 

export LD=bla ; cmake

Is there a variable controlling the linker used for executables? Thanks and best regards,
