It skips building it completely if configured with no-engine,
no-dynamic-engine or no-capieng. Otherwise it will attempt the build.
Inside e_capi.c it performs various compile time checks to determine
whether its got everything it needs to produce the engine. If it doesn't
then it just ends up building a dummy engine that doesn't do anything.
