Maybe fix hxtorch build
This adds googletest's lib/lib64 install folder explicitly to the list of libraries (it should be found in the code block above… but isn't).
- We fix something in the
hxtorch
build configuration, but this should not have had any consequences… - We update pynn-brainscales to align with the
hxtorch
software state (same UHEI-server-side experiment service used → version compatibility needed)
