| 2 | # FindWinSock | |
| 3 | # -------- | |
| 4 | # | |
| 5 | # Find the native realtime includes and library. | |
| 6 | # | |
| 7 | # IMPORTED Targets | |
| 8 | # ^^^^^^^^^^^^^^^^ | |
| 9 | # | |
| 10 | # This module defines :prop_tgt:`IMPORTED` target ``WINSOCK::WINSOCK``, if | |
| 11 | # WINSOCK has been found. | |
| 12 | # | |
| 13 | # Result Variables | |
| 14 | # ^^^^^^^^^^^^^^^^ | |
| 15 | # | |
| 16 | # This module defines the following variables: | |
| 17 | # | |
| 18 | # :: | |
| 19 | # | |
| 20 | # WINSOCK_INCLUDE_DIRS - where to find winsock.h, etc. | |
| 21 | # WINSOCK_LIBRARIES - List of libraries when using librt. | |
| 22 | # WINSOCK_FOUND - True if realtime library found. | |
| 23 | # | |
| 24 | # Hints | |
| 25 | # ^^^^^ | |
| 26 | # | |
| 27 | # A user may set ``WINSOCK_ROOT`` to a realtime installation root to tell this | |
| 28 | # module where to look. | |
