It is not always clear cut what is basic and what is a plugin. The only real core libraries are libCint and libCore. Libraries like libHist and libMatrix are always available but are not needed when not doing e.g. histogramming or lin algebra. Typically these libraries can be always built since they don't depend on external packages and just need a C++ compiler. Plugins are typically libraries that depend on some external library or libraries, like the SQL Server plugins or the remote file access plugins
