Description

Trying to build Mesos using cmake with the options

cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_SSL=1 -DENABLE_LIBEVENT=1

fails due to the following:

[  1%] Building C object CMakeFiles/event_extra.dir/bufferevent_openssl.c.o

Since the autotools build does not have issues when enabling libevent and ssl, it seems most likely that the `libevent-2.1.5-beta` version used by default in the cmake build is somehow connected to the error message.
