Add initial CMake support
 * Support for both in-source and out-of-source builds * Set library version to 0.12 to map Debian package * Add separate options to build tests, examples and documentation * Add pkgconfig lookup support (if installed with `make install`) * Add CMake lookup support (if isntalled with `make install`) * Add Google Test Source lookup * Add CTest support for running tests (use `make test` or `ctest -V`)
