I tried to build Qt(5.9.5 MSVC2015) project with cpprest sdk(2.9),

but it cause error at json.h

// Static factories

/// <summary>
/// Creates a null value
/// </summary>
/// <returns>A JSON null value</returns>
static _ASYNCRTIMP value __cdecl null();

/// <summary>
/// Creates a number value
/// </summary>
/// <param name="value">The C++ value to create a JSON value from</param>

error occured at [static _ASYNCRTIMP value __cdecl null();] C2059: syntax error: 'constant' C2238: unexpected token(s) preceding ';'

Is there any solution?
