I'm trying to compile freeswitch with module mod_flite. I have downloaded the module from  
     https://freeswitch.org/stash/scm/sd/libflite.git

Compiled it and installed successfully. Then trying to compile  freeswitch with mod_flite enabled, still I'm getting following error (for make),

making all mod_flite
make[4]: Entering directory `/usr/local/src/freeswitch/src/mod/asr_tts/mod_flite'
Makefile:886: *** You must install libflite-dev to build mod_flite.  Stop.
