FindDeckLinkSDK.cmake - Cmake module to find DeckLink SDK

This is a cmake module to find where the DeckLink SDK include file is installed. DeckLink SDK is the toolkit for BlackMagick Design Capture hardware.

This code sets the following variables:

  DeckLinkSDK_FOUND    = DeckLinkSDK is found.
  DeckLinkSDK_PATH     = where DeckLinkSDK is. Cashed.
  DeckLinkSDK_INCLUDE_PATH = path to where ${DeckLinkSDK_INCLUDE_FILE} is found.
  DeckLinkSDK_INCLUDE_FILE = DeckLinkAPI.idl (Win) or DeckLinkAPI.h (Mac/Linux).
  DeckLinkSDK_SRC_FILE = full path to DeckLinkAPIDispatch.cpp (Mac/Linux) or empty (Win).
  DeckLinkSDK_LIBS     = external libraries to link for target.
  DeckLinkSDK_DEF      = additional compiler flags.

If a system environment variable either of DECKLINK_SDK_DIR, BLACKMAGIC_SDK_DIR, DECKLINK_DIR or BLACKMAGIC_DIR set, it looks at paths from it.

Typical CmakeLists.txt snippet is;

    FIND_PACKAGE(DeckLinkSDK REQUIRED)
    IF(DeckLinkSDK_FOUND)
      INCLUDE_DIRECTORIES("${DeckLinkSDK_INCLUDE_PATH}")
      IF   (COMPILE_DEFINITIONS)
        SET(COMPILE_DEFINITIONS "${COMPILE_DEFINITIONS};${DeckLinkSDK_DEF}")
      ELSE (COMPILE_DEFINITIONS)
        SET(COMPILE_DEFINITIONS ${DeckLinkSDK_DEF})
      ENDIF(COMPILE_DEFINITIONS)
      ADD_EXECUTABLE(${your_app} ${your_srcs} "${DeckLinkSDK_SRC_FILE}")
      TARGET_LINK_LIBRARIES(${your_app} ${your_libs} "${DeckLinkSDK_LIBS}")
    ENDIF(DeckLinkSDK_FOUND)

You do the following in your DeckLink related sources;

    #include "DeckLinkSDK.h"

You can optionally provide version argument, for example;

    FIND_PACKAGE(DeckLinkSDK 10.5 REQUIRED)

will ensure the version of the SDK is greater than or equal to 10.5 (e.g., 10.4.99 will produce an error.)
