How to use the library on Windows 10 VS2015

1. Extract the zip file in the directory you preferred.
2. In your project, add $VAS_INSTALL_DIR\include to the ‘C/C++ - General - Additional Include Directories’ of properties
3. In your project, add $VAS_INSTALL_DIR\lib\intel64 to the ‘Linker - General - Additional Library Directories’ of properties
4. In your project, add the VAS libraries you want to use to the ‘Linker - Input - Additional Dependencies’ of properties
5. Add ‘$VAS_INSTALL_DIR\bin\intel64’ to the system path of environment variable

How to use the library on Linux

1. Extract the zip file in the directory you preferred.
2. Execute ‘source $VAS_INSTALL_DIR/bin/setupvars.sh’ on the terminal.
3. Add -I$VAS_INSTALL_DIR/include to the compiler flag.
4. Add -L$VAS_INSTALL_DIR/lib/x64 to the compiler flag.
5. Add the VAS libraries you want to use with -l option to the compiler flag. ex) -lvasfd
   compiler example) g++ your_source.cpp -std=c++11 {any other compiler option} -Imyinstall/include -Lmyinstall/lib/x64 -lvasfd -lvasfr
