including libcurl in CMake Env

Question

I use a Cmake build env, which generates Make files. I wanted to include libcurl library as I am getting a link error with curl APIs. Where to include libcurl library for static linking.

Build error Log:

In your cmake file(CMakelists.txt), you have to add a link_directories, for example:

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