replace dl library with CMAKE_DL_LIBS

Browse Source 
Some platforms do not have -ldl, specifically in this case freebsd.
The CMAKE_DL_LIBS is part of standard cmake and is supported
in the cmake_minimum_required() in the top level CMakeLists.txt
CMAKE_DL_LIBS will be -ldl on platforms that support it, or empty.
