Compiling ugcore without plugins fails

[miho]

When compiling ug4 via:

ughub/ughub init
ughub/ughub install ugcore
mkdir build && cd build && cmake ../ -DTARGET=ugshell

The following error message is shown (on Linux and OS X with CMake 3.x):

-- Info: Enabled plugins:

-- Hint: To enable/disable a plugin 'PLUGIN_NAME' use the cmake option: -DPLUGIN_NAME=ON/OFF
