C++ library does not export static functions like lib_init()

[Stephen Woods]

Version 1.1 (+ earlier) (Windows)

mosquittopp.h missing mosqpp_EXPORT on following static functions

const char *strerror(int mosq_errno);
const char *connack_string(int connack_code);
int sub_topic_tokenise(const char *subtopic, char ***topics, int *count);
int sub_topic_tokens_free(char ***topics, int count);
int lib_version(int *major, int *minor, int *revision);
int lib_init();
int lib_cleanup();
int topic_matches_sub(const char *sub, const char *topic, bool *result);

should be

mosqpp_EXPORT const char *strerror(int mosq_errno);
mosqpp_EXPORT const char *connack_string(int connack_code);
mosqpp_EXPORT int sub_topic_tokenise(const char *subtopic, char ***topics, int *count);
mosqpp_EXPORT int sub_topic_tokens_free(char ***topics, int count);
mosqpp_EXPORT int lib_version(int *major, int *minor, int *revision);
mosqpp_EXPORT int lib_init();
mosqpp_EXPORT int lib_cleanup();
mosqpp_EXPORT int topic_matches_sub(const char *sub, const char *topic, bool *result);

Can confirm with dumpbin /exports mosquittopp.dll

Work around is to call the mosquitto version e.g.

 #ifdef _WIN32 // lib_init() not in windows lib?
  mosquitto_lib_init();
 #else
  lib_init();
 #endif

Though need to link against both mosquittopp and mosquitto

I agree, this is incorrect. I've made a commit that fixes it for 1.1.1:

Thanks for the report!
