config.status: executing libtool commands
configure: WARNING: No QT support found.
*** The GUI (graphical user interface) will not be built!
*** Note: most linux distributions split qt into two packages:
*** one containing only the libraries needed to run binary qt
*** applications and one containing all the headers and tools
*** needed to compile qt applications from source.
*** Obviously, you need *both* packages in that case.
*** If you know you have qt installed, try to run configure
*** again with the "--with-qt-(lib|bin|inc)dir=<YOUR QT DIRS>" flags.
*** For details see "./configure --help".
