Description:
libevent.a is supposed to be built only when needed, e.g. by xplugin. It seems the cmake dependency mechanism doesn't work, at least not on OS X with Cmake 3.4.1 and clang. 

How to repeat:
Run cmake on OS X with cmake 3.4.1 and then build with xcodebuild, making sure you don't specify -DWITH_RAPID=0.

Upgrading to the latest CMake (3.6.0-rc3 for MacOS) made no difference.

It seems PB2 build for macOS work because they use the Make backend.
This cmake issue may explain what we see:

Noted in 8.0.0 changelog.

libevent was built on OS X even when not needed.
