[CMake] cmake-2.8.12: generator expression error when linker flags have comma

[Nick Hutchinson]

target_link_libraries() is supposed to work for linker flags as well:

cmake version 2.8.12
  target_link_libraries
       Link a target to given libraries.

         target_link_libraries(<target> [item1 [item2 [...]]]
                               [[debug|optimized|general] <item>] ...)

       Specify libraries or flags to use when linking a given target.  The
       named <target> must have been created in the current directory by a
       command such as add_executable or add_library.  The remaining
       arguments specify library names or flags.
