Find and link to external libraries in user code
When MeteoIO has been compiled and linked to some third party libraries (for example libproj), linking to MeteoIO in end user code gets tricky: the end user must also link his/her code to the third party libraries. This is very inconvenient as the end user has no way to know for sure beforehand which third party libraries are required and would need to figure out which other compilation (actually linking) flags are required.
Finding a way to detect for any given MeteoIO library which dependencies are required or avoiding the need to these extra linking requirements would be a major improvement...
