how to enable mongodb support in coturn server

[sara waheed]

i am using coturn and i want to use mongodb as a database 

when i run the turnserver it shows 

    SQLite supported, default database location is /var/lib/turn/turndb

    0: Redis supported

    0: PostgreSQL supported

    0: MySQL supported

    0: MongoDB is not supported

    0: 

    0: Default Net Engine version: 3 (UDP thread per CPU core)

i have installed coturn 

using this command 

    sudo apt-get install coturn

and the coturn docs https://github.com/leecade/coturn/blob/32d52f5006e1d9cdce4060464cabe7e261502177/INSTALL#L377 says 

> mongo-c-driver packages are not available "automatically".  MongoDB

> support will not be compiled, unless you install it "manually" before

> the TURN server compilation. Refer to 

> https://github.com/mongodb/mongo-c-driver for installation

> instructions of the driver.

and tried to install mongo c driver by following this guide http://mongoc.org/libmongoc/current/installing.html

**Install libmongoc with a Package Manager**

    apt-get install libmongoc-1.0-0

**Build environment on Unix**

On Debian / Ubuntu:

    $ sudo apt-get install cmake libssl-dev libsasl2-dev

**Configuring the build**

Preparing a build from a git repository clone

    $ git clone https://github.com/mongodb/mongo-c-driver.git

    $ cd mongo-c-driver

    $ git checkout 1.17.0  # To build a particular release

    $ python build/calc_release_version.py > VERSION_CURRENT

    $ mkdir cmake-build

    $ cd cmake-build

    $ cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..

**Executing a build**

Building on Unix, macOS, and Windows (MinGW-W64 and MSYS2)¶

    $ cmake --build .

    $ sudo cmake --build . --target install

and 

`~/mongo-c-driver/cmake-build$`cmake --build . help

returned 

    Unknown argument help

    Usage: cmake --build <dir> [options] [-- [native-options]]

    Options:

      <dir>          = Project binary directory to be built.

      --target <tgt> = Build <tgt> instead of default targets.

                       May only be specified once.

      --config <cfg> = For multi-configuration tools, choose <cfg>.

      --clean-first  = Build target 'clean' first, then build.

                       (To clean only, use --target 'clean'.)

      --use-stderr   = Ignored.  Behavior is default in CMake >= 3.0.

      --             = Pass remaining options to the native tool.

and 

**Generating the documentation**

    cmake -DENABLE_MAN_PAGES=ON -DENABLE_HTML_DOCS=ON ..

returned

    -- No CMAKE_BUILD_TYPE selected, defaulting to RelWithDebInfo

    file VERSION_CURRENT contained BUILD_VERSION 1.17.0

    -- Build and install static libraries

      -- Using bundled libbson

    libbson version (from VERSION_CURRENT file): 1.17.0

    --     struct timespec found

    Adding -fPIC to compilation of bson_static components

    CMake Error at CMakeLists.txt:10 (_message):

    cmake --build . --target mongoc-doc

    make: *** No rule to make target 'mongoc-doc'.  Stop.

and when i restart the coturn server it still shows that mongodb is not supported

how can i resolve this issue
