On my x86_64 Gentoo Linux, the CMake build won't find libevent because Gentoo wraps include files via multilib-aware wrappers. This means that the "real" include file lives in /usr/include/x86_64-pc-linux-gnu/event2/event-config.h , and that there's a proxy file at /usr/include/event2/event-config.h which check the compile target's architecture and includes the real file from a correct directory. In other words, nghttp2's CMake FindLibevent.cmake reads a wrong file and ends up not detecting the libevent's version. This patch fixes it by simply using the version reported by pkg-config as the libevent's version if the original method fails. I will be happy to change this patch to always check version from pkg-config if you're OK with that. Signed-off-by: Jan Kundrát <jan.kundrat@cesnet.cz>
