Linking issue with Raspbian

If you are using a Raspberry Pi with Raspbian you might encounter a linking problem with Assimp that looks like:

~/ros_catkin_ws/devel_isolated/collada_urdf/lib/libcollada_urdf.so: undefined reference to `typeinfo for Assimp::IOSystem'
collect2: error: ld returned 1 exit status

A work-around consists of compiling and installing Assimp latest version:

mkdir -p $HOME/libraries/assimp-3.3.1/build_release
cd $HOME/libraries/assimp-3.3.1/
wget https://github.com/assimp/assimp/archive/v3.3.1.zip
unzip v3.3.1.zip
rm v3.3.1.zip
mv v3.3.1 src
cd build_release
cmake ../src -DCMAKE_BUILD_TYPE=Release -DASSIMP_BUILD_TESTS=False
make -j3

sudo make -j3 install

Make sure you reconfigure the catkin workspace (or just delete the build files) so that the newest Assimp version is found before compiling again.
