问题
I have been struggling for the last 8 hours to find information on how to reference a library in a C project on Windows built with CMake, specifically cURL.
I have downloaded version 7.67 cURL source from the website, and then went used the visual studio developer command prompt to compile the CMake project into a build folder using the standard method of:
cd winbuild
nmake /f Makefile.vc mode=dll
Which outputs three curl folders, one of them called "libcurl-vc-x86-release-dll-ipv6-sspi-winssl". In that folder contains a lib, a bin, and an include folder.
I built my C project with CLion and this is the CMake file that is generated.
cmake_minimum_required(VERSION 3.15)
project(hello_world C)
set(CMAKE_C_STANDARD 99)
add_executable(hello_world main.c)
How do I use my compiled CURL in my C project with CMake properly?
回答1:
I finally solved this issue by creating a cmake folder at the C: directory, and copying in the built curl CMake project folder.
The issue was that there weren't any specific tutorials that I found on how to reference projects on Windows for CMake, specifically the curl project.
Fortunately, I found this post which specified an issue I had in referencing the include folder and .lib directory separately. How to link shared library *dll with CMake in Windows
cmake_minimum_required(VERSION 3.15)
project(hello_world C)
set(CMAKE_C_STANDARD 99)
include_directories("C:/cmake/libcurl-vc-x86-release-dll-ipv6-sspi-winssl/include")
link_directories("C:/cmake/libcurl-vc-x86-release-dll-ipv6-sspi-winssl/lib")
add_executable(hello_world main.c)
set( LIBS libcurl )
target_link_libraries(hello_world ${LIBS} )
Now the code compiles and runs succesfully. I don't believe this is the proper method of doing this though, any help would be appreciated.
