TFLITE for linux

source: https://stackoverflow.com/questions/55125977/how-to-build-tensorflow-lite-as-a-static-library-and-link-to-it-from-a-separate

First compile the static library:

$ ./tensorflow/lite/tools/make/download_dependencies.sh
$ make -f tensorflow/lite/tools/make/Makefile

**If the 'download_dependencies.sh' script fails in the tensorflow version you are using, try to download the last version of this file from the tensorflow repository.

By default make would just do native build. The output library will be stored as

<tensorflow-root>/tensorflow/lite/tools/make/gen/<platform>/lib/libtensorflow-lite.a

And the external dependencies with their headers would go into

<tensorflow-root>/tensorflow/tensorflow/lite/tools/make/downloads 

(for example flatbuffers headers are in <tensorflow-root>/tensorflow/tensorflow/lite/tools/make/downloads/flatbuffers/include).
