Hi guys,

i get the compile error:

-- Configuring incomplete, errors occurred!

i am using hydro and i have installed qt_build and qt-ros by running the two following lines:

sudo apt-get install ros-hydro-qt-build
sudo apt-get install ros-hydro-qt-build

My CMakeList.txt looks like the following:

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
include(ExternalProject)

# Set the build type.  Options are:

#  RelWithDebInfo : w/ debug symbols, w/ optimization
#  MinSizeRel     : w/o debug symbols, w/ optimization, stripped binaries

Has someone a idea, what is missing or what the error means?

Thanks.
