Build error on termux app

When I build drogon on "make install" command, cause a build error.

When I first enter termux.  I entered these commands.

### Build Dependencies

`pkg update`

`pkg install git`

`pkg install build-essential` 

`pkg install jsoncpp-static`

`pkg install libuuid`

`pkg install zlib-static`

`pkg install openssl-static`

`git clone https://github.com/drogonframework/drogon`

`cd drogon`

`git submodule update --init`

`mkdir build`

`cd build`

`cmake ..`

`make && make install`

I think its possible building success. However I got these errors!!
