R CUDA support in new build structure

[peterwittek]

With commit 73abe64, the scripts that were floating around for the R interface were merged to a Makefile target. To build the source distribution for R, just issue make r.

The R directory contains a configure script by default. If we build the module without CUDA, the script just exits and the usual R compilation procedure starts. To build with CUDA, you have to supply a parameter to the R install system:

R CMD INSTALL Rsomoclu_1.5.tar.gz --configure-args=/path/to/cuda

The .so file is built correctly and the module is installed, but the test fails. Please look into this.

R CMD INSTALL Rsomoclu_1.5.tar.gz --configure-args=/path/to/cuda
doesn' t build for me. After some changes as 250ced3 shows, I still get:

g++ -shared -L/usr/lib64/R/lib -Wl,-O1,--sort-common,--as-needed,-z,relro -o Rsomoclu.so Rsomoclu.o denseCpuKernels.o sparseCpuKernels.o mapDistanceFunctions.o training.o uMatrix.o -I/home/gsc/R/x86_64-unknown-linux-gnu-library/Rcpp/include -DHAVE_R -DCUDA denseGpuKernels.cu.co -lgomp -L/opt/cuda/lib64 -lcudart -lcublas -L/usr/lib64/R/lib -lR

My bad, 56be992 fixes it.

[xgdgsc]

With 833b0d6, it builds and runs fine in both kernels for me.

I just checked, it works perfectly. Thank you.
