CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake:26 (find_package):
  Could not find a package configuration file provided by "Qt5WebSockets"
  with any of the following names:

    qt5websockets-config.cmake

  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 had got same problem :S

I already installed the 2 new dependencies
the GLEW and the QT5-websockets thingy.

My cmake outputs exact same config errors.

If you figure it out shoot a note. I'll do the same here.

This did help:

FG_CMAKEARGS="-DENABLE_FGQCANVAS=off"

[IAHM-COL]

ok.

I just git pulled both simgear and flightgear. Then compiled on that order.
The last commits by James Turner apparently fixed the error, and compiled with the FGQcanvas as well

In other words we'll need to verify how to satisfy the missing dependency if we want the FGQcanvas built. But for now it compiles.

    Abandon FGQCanvas build if QtWebSockets is missing.
   
    Should avoid build pain for people with older Qt5 installs or who
    don’t have the web-sockets development package available.

I was able to compile now even without the last conditional build commit by James, by installing this package
