在CMake Env中包括libcurl

Question

我使用Cmake構建環境，該環境生成Make文件。 我想包含libcurl庫，因為我收到了curl API的鏈接錯誤。 包含libcurl庫以進行靜態鏈接的位置。

生成錯誤日志：

在cmake文件（CMakelists.txt）中，您必須添加一個link_directories，例如：

 link_directories(your_libfile_directory) add_executable(executable_name file_c_cpp) target_link_libraries(executable_name curl)
