Fixes OpenDSSC installation: correct find condition and add to linker path

[leonardocarreras]

The OpenDSCC installs in a non-usual path.

The current check with find will always install because is not looking into the path where it gets installed.

The symbols needed are not found by the linker, so this is added.

Hi @leonardocarreras,

I think this should already have been resolved by this change which I merged a few days ago:
8bc1fe2#diff-49cac9549226aeff7ab6461609d9afc6d8bec062d76414c79007b101d5c2eda6R68

I am not a big fan of modifying the linker search path in deps.sh, since this is mixing up concerns:
https://github.com/VILLASframework/node/pull/910/files#diff-3702afcced7ceb56a7ccf7ebb5f0cfd309d51c83ba2cc77786507b02635eb291R506

A better solution, would be to add some more patches to install the library in the correct location. Like we already do here with other patches for OpenDSSC:

node/packaging/deps.sh

Line 492 in 366df98

for i in ${SOURCE_DIR}/patches/*-opendssc-*.patch; do patch --strip=1 --binary < "$i"; done

Hi @stv0g! I understand your point, what happens is that when just installing villas dependencies with the script in your own machine or in a container, you do not realize that there is a problem until later (in my experience villas compiles, but does have a runtime problem)... I will then keep doing the same in the container for dpsim that uses villas...
