### Build Dependencies
* c-ares (libc-ares-dev on Debian based systems) - only when compiled with `make WITH_SRV=yes`
* cJSON - for client JSON output support. Disable with `make WITH_CJSON=no` Auto detected with CMake.
* libwebsockets (libwebsockets-dev) - enable with `make WITH_WEBSOCKETS=yes`
* openssl (libssl-dev on Debian based systems) - disable with `make WITH_TLS=no`
* xsltproc (xsltproc and docbook-xsl on Debian based systems) - only needed when building from git sources - disable with `make WITH_DOCS=no`
* pthreads - for client library thread support. This is required to support the
`mosquitto_loop_start()` and `mosquitto_loop_stop()` functions. If compiled
without pthread support, the library isn't guaranteed to be thread safe.
* uthash / utlist - bundled versions of these headers are provided, disable their use with `make WITH_BUNDLED_DEPS=no`
* cJSON - for client JSON output support. Disable with `make WITH_CJSON=no` Auto detected with CMake.
* xsltproc (xsltproc and docbook-xsl on Debian based systems) - only needed when building from git sources - disable with `make WITH_DOCS=no`
Equivalent options for enabling/disabling features are available when using the CMake build.
