FindAdrienne.cmake

# - try to find Adrienne Electronics Corporation timecode card library
#
# SDK available from the manufacturer: http://www.adrielec.com/
#
# Cache Variables: (probably not for direct use in your scripts)
#  ADRIENNE_INCLUDE_DIR
#  ADRIENNE_LIBRARY
#  ADRIENNE_RUNTIME_LIBRARY
#  ADRIENNE_INCLUDE_FILE
#
# Variables you might use in your CMakeLists.txt:
#  ADRIENNE_FOUND
#  ADRIENNE_INCLUDE_DIRS
#  ADRIENNE_LIBRARIES
#  ADRIENNE_RUNTIME_LIBRARIES - the AEC_NTTC.dll file
#  ADRIENNE_RUNTIME_LIBRARY_DIRS
#
#  ADRIENNE_INCLUDE_FILENAME - this is probably AEC_NTTC.h, but it might also
#    be AECINTTC.H.
#
#  ADRIENNE_INCLUDE_HAS_EXTERN_C - Some (most) versions of the header already
#    wrap their definitions in extern "C" { }, but some do not.
#
#  ADRIENNE_DEFINITIONS - defines a quoted ADRIENNE_INCLUDE_FILENAME as above,
#    so you can write a line like #include ADRIENNE_INCLUDE_FILENAME
#    Also defines ADRIENNE_BEFORE_INCLUDE and ADRIENNE_AFTER_INCLUDE to handle
#    adding extern "C" { and } if the header file doesn't do so itself.
#
# Variables that might be set by the user in the gui/command line to help
# find the library:
#  ADRIENNE_ROOT_DIR - root of an Adrienne CD, disk, or extracted/copied contents
#    thereof.
#
# Requires these CMake modules:
#  FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
