Hi, What library variants should be build on Windows by default? Currently it builds: --build-type=<type> Build the specified pre-defined set of variations of the libraries. Note, that which variants get built depends on what each library supports. -- minimal -- (default) Builds a minimal set of variants. On Windows, these are static multithreaded libraries in debug and release modes, using shared runtime. On Linux, these are static and shared multithreaded libraries in release mode. Personally I use a static-release runtime often (for simple deployments). What variants do others use and what should be build by default? Greetings, -- Olaf
