Use QtCreator to develop OpenViBE in 2017 on Linux

Note: This tutorial does not use the meta repository. It uses the latest OpenViBE 2.0.0 repositories with the multi-repository build. It is based on QtCreator 4.4.1 (the currently latest stable release). It will work on the 4.5 version, however this one seems to not currently work very well on Linux. It is possible to simplify this installation a LOT if you only wish to build the OpenViBE component and wish to use the default SDK (Kernel, Modules, base plugins.
