Cannot generate custom msgs anymore, kinetic, 16.04

edit

Hey there, from today I cannot build anymore my custom msgs package. Anyone of you had such an error before:

catkin build ball_tracking_msgs

/bin/sh: 1: Syntax error: "(" unexpected
make[2]: *** [CMakeFiles/_ball_tracking_msgs_generate_messages_check_deps_BallState] Error 2
make[1]: *** [CMakeFiles/_ball_tracking_msgs_generate_messages_check_deps_BallState.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [all] Error 2

I had this error never before.... and on other machines my packages builds.... I installed blender today like this:

sudo apt-get update && sudo apt-get install python-software-properties
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:thomas-schiex/blender
sudo apt update && sudo apt install blender

Is the above blender installation responsible for my errors?

cmake_minimum_required(VERSION 2.8.3)

set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}")

BallState.msg:
