I don't think this is a CMake question.
If you need getline on OS X then may be you'll have to provide an
implementation when you are compiling on OS X?
see:

In a CMakeLists.txt one usually do something like:

IF(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
  list(APPEND SOURCES  mygetline.c)
endif()

Have a look at the Wiki entries too:
