[R] Install OpenCL

[Quirin Stier]

Thanks a lot for your help again.

Installing the package with INSTALL_opts = '--no-test-load' enables
package installation. Doing that plus analyzing the OpenCL.dll with the
dependency walker software for both the original OpenCL.dll (which
RStudio apparently found while installing) and a second OpenCl.dll from
the www yields following output (which is the same for both OpenCl.dll
attempts):

Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing
export function in an implicitly dependent module.
Error: A circular dependency was detected.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module.

Nota: NVIDIA GPU Computing Toolkit does not contain any OpenCL.dll, only
the OpenCL.h (required for the includes) and a OpenCL.lib (maybe not
important)
