4# - Try to find the gpgme library
5#
6# Algorithm:
7# - Windows:
8# On Windows, there's three gpgme variants: gpgme{,-glib,-qt}.
9# - The variant used determines the event loop integration possible:
10# - gpgme: no event loop integration possible, only synchronous operations supported
11# - gpgme-glib: glib event loop integration possible, only asynchronous operations supported
12# - gpgme-qt: qt event loop integration possible, only asynchronous operations supported
13# - GPGME_{VANILLA,GLIB,QT}_{FOUND,LIBRARIES} will be set for each of the above
14# - GPGME_INCLUDES is the same for all of the above
15# - GPGME_FOUND is set if any of the above was found
16# - *nix:
17# There's also three variants: gpgme{,-pthread,-pth}.
18# - The variant used determines the multithreaded use possible:
19# - gpgme: no multithreading support available
20# - gpgme-pthread: multithreading available using POSIX threads
21# - gpgme-pth: multithreading available using GNU PTH (cooperative multithreading)
22# - GPGME_{VANILLA,PTH,PTHREAD}_{FOUND,LIBRARIES} will be set for each of the above
23# - GPGME_INCLUDES is the same for all of the above
24# - GPGME_FOUND is set if any of the above was found
