Build error on termux app

[321qwedsa000]

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!!

The issue is that Android NDK has shady C++ support. It does have the filesystem header but doesn't ship the library (android/ndk#609). I think I'll add a workarround in CMake to force boost on Android.
