speech

This project aims to develop a qt-based generic serialization/deserialization mechanism and strongly-typed messaging over network.

The library is composed of only headers. We aim to follow modern c++ approach.

It is under GNU General Public License.

CMake

speech library uses CMake build system and follows modern-cmake paradigm.

QMake

speech library doesn't use qmake as build system currently but it mıght be supported at future.

Dependencies and required(recommended) tools

• Qt5
• CMake
• A compiler which supports C++17

Compiler Support

• GCC ( Tested 7.4.0 )
• MinGW ( Tested 7.3.0 )
• VS Compiler ( Tested MSVC 2017 )
• Clang ( Not Tested )
