Allow "installation" of CUDA Samples with CMake

[Thyre]

Before the switch to CMake, the CUDA Samples were all built and stored in a pre-defined directory:

<some prefix>/bin/%s/linux/release/*

With the change to CMake however, this has changed. Only a few select programs can actually be installed.
All others stay in the build folder.

In cases where one want to provide the pre-built examples, e.g. for EasyBuild, one would now need to gather all the binaries (and potential input files) from both the source and build folder to achieve the same.

I would therefore like to request to include an option to install the CUDA Samples via standard CMake procedures, to reduce the work load when one wants to provide these samples.

Thanks for your feedback. We are working on this and will add this option back in the future release.
