# - Try to find the assuan library
|
||
|
|
#
|
||
|
|
# Algorithm:
|
||
|
|
# - Windows:
|
||
|
|
# On Windows, there's three assuan variants: assuan{,-glib,-qt}.
|
||
|
|
# - The variant used determines the event loop integration possible:
|
||
|
|
# - assuan: no event loop integration possible, only synchronous operations supported
|
||
|
|
# - assuan-glib: glib event loop integration possible, only asynchronous operations supported
|
||
|
|
# - assuan-qt: qt event loop integration possible, only asynchronous operations supported
|
||
|
|
# - ASSUAN_{VANILLA,GLIB,QT}_{FOUND,LIBRARIES} will be set for each of the above
|
||
|
|
# - ASSUAN_INCLUDES is the same for all of the above
|
||
|
|
# - ASSUAN_FOUND is set if any of the above was found
|
||
|
|
# - *nix:
|
||
|
|
# There's also three variants: assuan{,-pthread,-pth}.
|
||
|
|
# - The variant used determines the multithreaded use possible:
|
||
|
|
# - assuan: no multithreading support available
|
||
|
|
# - assuan-pthread: multithreading available using POSIX threads
|
||
|
|
# - assuan-pth: multithreading available using GNU PTH (cooperative multithreading)
|
||
|
|
# - ASSUAN_{VANILLA,PTH,PTHREAD}_{FOUND,LIBRARIES} will be set for each of the above
|
||
|
|
# - ASSUAN_INCLUDES is the same for all of the above
|
||
|
|
# - ASSUAN_FOUND is set if any of the above was found
|
||
|
|
#
|
||
|
|
|
||
|
|

|
|
# THIS IS ALMOST A 1:1 COPY OF FindGpgme.cmake.
|
||
|
|
# Any changes to here likely apply there, too.
|
||
|
|
# Therefore, the as-yet-nonexistant -glib nd -qt flavours are only commented out, not removed.
