For now, GLEW is indeed required, and even installing it isn't enough:

  Add the installation prefix of "Qt5WebSockets" to CMAKE_PREFIX_PATH or set
  "Qt5WebSockets_DIR" to a directory containing one of the above files.  If
  "Qt5WebSockets" provides a separate development package or SDK, be sure it
  has been installed.

I believe GLEW is supposed to be optional, what about Qt5WebSockets?
