0027398: Integrate Qt Browser Widget to Open CASCADE Technology
The following implementation has been made: - CMake procedure is extended to compile Qt tools. This is optional and is handled by USE_QT_TOOLS option(OFF by default) - It is possible to build Qt tools using Qt5 or Qt4, it is settled with USE_QT4 option. - Sample of DFBrowser tool is available in samples/tools/TInspectorEXE. It is build with tools, executable is placed in binaries. To start the sample, use dfbrowser.bat command. - DFBrowser tool may be started from DRAW
