I'm trying to build a cmake project that uses WinHTTP. Below is my cmakelists.txt file

cmake_minimum_required(VERSION 3.19)
project(Mandarin_EXE_Updator)

set(SOURCE_FILES main.cpp)

set(WIN32 True)

OPTION(WINHTTP ON)

add_executable(Mandarin_Updator WIN32 ${SOURCE_FILES})

target_link_libraries(winhttp)

I've tried doing link_libraries and target_link_libraries but with no luck. I think i need to use link_libraries, but with the full path to the lib file.

below is the output of cmake --build .

you need to specify the target for `target_link_libraries`, also try `winhttp.lib` – Alan Birtles Mar 29 '21 at 07:06
@AlanBirtles I've just tried that and i still get the same error – Shravan Mandava Mar 29 '21 at 07:12
and what error is that? – Alan Birtles Mar 29 '21 at 07:14
I've edited the original post to contain my build error – Shravan Mandava Mar 29 '21 at 07:22
presumably you haven't defined a `WinMain` function or if you meant to create a console application remove `WIN32` from `add_executable` – Alan Birtles Mar 29 '21 at 07:27
