Using Qt Libraries in ROS

Modify the CMakeLists.txt file to include the qt library while compilation. Add the following lines at the end of the default generated CMakeLists.txt file -

find_package(Qt4)
include(${QT_USE_FILE})
# This is necessary as all ui files etc will get dumped in the bottom of the
# binary directory.
include_directories(${CMAKE_CURRENT_BINARY_DIR})

file(GLOB_RECURSE QT_MOC RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS include/local/*.hpp)

QT4_ADD_RESOURCES(QT_RESOURCES_CPP ${QT_RESOURCES})
