error at build matmul example with cuda

[SimeonEhrig]

I tried to build the matmul example with the instruction in INSTALL.md (and an own project with a simple hello world main.cpp) and got follow error:

/home/simeon/libraries/cupla/alpaka/include/alpaka/vec/Vec.hpp(461): error: no instance of function template "alpaka::vec::Vec<TDim, TSize>::foldrAll [with TDim=cupla::AlpakaDim<1U>, TSize=cupla::MemSizeType]" matches the argument list

  /home/simeon/libraries/cupla/build_matmul_cuda/CMakeFiles/matrixMul.dir/__/__/__/src/./matrixMul_generated_memory.cpp.o

I used export CUPLA_ROOT=$HOME/libraries/cupla and cmake $CUPLA_ROOT/example/CUDASamples/matrixMul -DALPAKA_ACC_GPU_CUDA_ENABLE=ON && make -j4.

If I used -DALPAKA_ACC_CPU_B_SEQ_T_OMP2_ENABLE=ON instead -DALPAKA_ACC_GPU_CUDA_ENABLE=ON, the build was fine.

System: Ubuntu 16.04, gcc 5.4, Cuda 8

I will check it on Monday.

Could you please test if the update to the latest stable alpaka version solves the issue. I added a pull request #63 and will merge it to the dev as soon as the CI is finished.

Please run git submodule update after the rebase.

[SimeonEhrig]

Yes, it works with the example and in my project.

issue is solved with #63
