OpenCL examples do not compile with SDx 2018.3

[Moschn]

I am using ubuntu 18.04 and SDx 2018.3. The OpenCL examples in this repo do not compile on my machine. E.g., running make clean all in ocl/getting_started/hello_vadd_ocl results in

aarch64-linux-gnu-g++ -o 'build/zcu102_hw/vadd' src/host.cpp ../../../libs/xcl2/xcl2.cpp -I/opt/Xilinx/SDx/2018.3/runtime/include/1_2/ -I/opt/Xilinx/SDx/2018.3/Vivado_HLS/include/ -O2 -g -Wall -std=c++14  -lxilinxopencl -lpthread -lrt -ldl -lcrypt -lstdc++ -L/opt/Xilinx/SDx/2018.3/runtime/lib/aarch64 -I../../../libs/xcl2

 #include <CL/cl2.hpp>
          ^~~~~~~~~~~~
compilation terminated.

To fix this, I tried to add another include directive to the compiler (i.e., -I/usr/include since cl2.hpp is in /usr/include/CL/cl2.hpp) but then the compiler complains about float128 amongs other errors:
