- Library linking: there must not be "target_link_library()" for libraries,
only when building binaries. Avoid clashes between static module
or class variables, and strange reinitialisation of those variables.
- Change: Boost is now always linked staticly.
* ./crlcore:
- Change: In System, static initialisation problem again, there seems to
be a race between it and boost::filesystem, make the singleton creation
"at first call" again. Triggers the System singleton creation in
AllianceFramework to spare the user the need to explicitly doing it.
- New: In Utilities, automatically adds the "site-packages" PYTHONPATH
component, guessed from CORIOLIS_TOP.
