To create the duk_config.h file change into the directory ${DUKTAPE}/tools and run the
following Python command (you can copy/paste it):
python2 configure.py \
--output-directory=out \
--omit-removed-config-options --omit-deprecated-config-options --omit-unused-config-options \
--emit-config-sanity-check \
--option-file ../config/examples/performance_sensitive.yaml \
--option-file ../config/examples/timing_sensitive.yaml
An 'extern "C"' block has to be added to the headers duk_logging.h, duk_module_duktape.h and
duk_v1_compat.h (from the directory ${DUKTAPE}/extras) to avoid C++ decoration of the function
names.
