set(CMAKE_REQUIRED_INCLUDES "sys/types.h")
CHECK_INCLUDE_FILES(netinet/tcp.h HAVE_NETINET_TCP_H)

./bin/cmake --help-module CheckIncludeFiles
      The following variables may be set before calling this macro to modify
        the way the check is run:

          CMAKE_REQUIRED_FLAGS = string of compile command line flags
          CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
          CMAKE_REQUIRED_INCLUDES = list of include directories
