vs使用libcurl(static library)，link时报错：

error LNK2001: unresolved external symbol __imp__curl_easy_perform  error LNK2001: unresolved external symbol __imp__curl_easy_setopt  error LNK2001: unresolved external symbol __imp__curl_easy_init  error LNK2001: unresolved external symbol __imp__curl_easy_cleanup

1、项目属性->link->input:

libcurl.lib ws2_32.lib winmm.lib wldap32.lib

2、项目属性->C/C++->Preprocessor->Definitions 增加:

BUILDING_LIBCURL

HTTP_ONLY
