faster. See https://github.com/matiasdelellis/pdlib/pull/2. Increase the version to 1.0.2 since this is a required function for our application and we must control it. Add more compilation info in php-info(), and print a final message with the build options when configure. Fix that when dlib is not installed, the configuration returns that it cannot find pkgconfig. See https://github.com/matiasdelellis/facerecognition/issues/261 Also implement the test on travis. See for example: (https://travis-ci.com/github/matiasdelellis/pdlib/builds/161854044)
