* Add BAC_ROUTING compile definition
* Reorder cmake
* Fix OpenSSL support: support both 1.0 and 1.1t pus
* Explicitly export symbols, hidden by default
* Build shared libraries on travis using cmake
* Learn Makefile about static library
* Fix build using mingw with cmake
* Do not cleanup twice or after potential free
* fix warnings indicated by scan-build lint tool
* add lint target to makefile using scan-build tool
* add lint into build script stages (note: uses scan-build-7)
* fix potential use of memory after it is freed
This way we hide the real build system and thus, can replace Makefiles
with Ninja and we won't have to change the build command.
--clean-first parameter will invoke clean target before building.
