LMMS now properly builds and runs with Qt5. Various deprecated functions had to be replaced like QString::toAscii()/fromAscii(). Also occurences of FALSE/TRUE have been replaced with false/true. LmmsStyle now derives from QProxyStyle and sets a style instance as base style (Plastique for Qt4, Fusion for Qt5). MOC files are not included anymore but added as regular source files. What's missing is support for embedding VST plugins into a subwindow inside LMMS on Linux/X11 due to missing QX11EmbedContainer class in Qt5. Build instructions can be found in INSTALL.Qt5 Minimum version requirement for Qt4 has been raised to 4.6.0 for best API compatibility between Qt4 and Qt5.
