Undefined references from iothub_client_properties.h when included in C++ source file

[D-r-P-3-p-p-3-r]

I got messages from the linker like

undefined reference to `IoTHubClient_Properties_Serializer_CreateReported(IOTHUB_CLIENT_PROPERTY_REPORTED_TAG const*, unsigned int, char const*, unsigned char**, unsigned int*)

undefined reference to `IoTHubClient_Properties_Serializer_Destroy(unsigned char*)'

when including iothub_client_properties.h in a C++ source code file.

The problem is that iothub_client_properties.h does not contain an extern "C" specification like

#ifdef __cplusplus
extern "C"
{
#endif

// ...

#ifdef __cplusplus
}
#endif

Including the file via

extern "C" {
#include <iothub_client_properties.h>
}

works but is ugly like hell.
