GATE: benchmarks and examples

[ocaisa]

Currently there's no integrated way to download and install the examples and benchmarks thats supported by GATEs CMake build process.
To do it in the easyconfig, the relevant options are:

configopts = " -DGATE_DOWNLOAD_BENCHMARKS_DATA=ON "
configopts += " -DGATE_DOWNLOAD_EXAMPLES_DATA=ON "
postinstallcmds = ["cp -r %(builddir)s/gate_v%(version)s/benchmarks %(builddir)s/gate_v%(version)s/examples %(builddir)s/gate_v%(version)s/ExternalData %(installdir)s"]

This is probably not so safe since there are symlinks in the dirs (though they all seem to be relative).

Using cp -a may be a better idea.

But we should support this via the GATE easyblock instead, so you can do:

with_benchmarks = True
with_examples = True
