    Setting the LD_LIBRARY_PATH environment variable is one option. For example:

    export LD_LIBRARY_PATH=/path/to/dir/with/libs:$LD_LIBRARY_PATH

    Another option is to set the RPATH of your Qt application during linking. Setting the RPATH to the value “$ORIGIN” will cause the dynamic linker to look in the same directory as your Qt application at runtime. For example, if using qmake, add the following snippet to your project file:

    unix:!mac{
  QMAKE_LFLAGS += -Wl,--rpath=\\\$\$ORIGIN
  QMAKE_LFLAGS += -Wl,--rpath=\\\$\$ORIGIN/lib
  QMAKE_LFLAGS += -Wl,--rpath=\\\$\$ORIGIN/libs
  QMAKE_RPATH=
}

    This will set the RPATH to “$ORIGIN:$ORIGIN/lib:$ORIGIN/libs”, meaning that the dynamic linker will first look in the location of your Qt application, then in a lib subdirectory at its location, then in a libs subdirectory at its location, and finally in any system defined locations.
