How to include a folder with headers?

Question

C++ / C#

Hello
In the folder with the compiler are the necessary files to work with winapi. I am writing through CLion and I need to somehow connect this folder, the environment does not want to index files connected via include

#include "tlhelp32.h"
CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL); // Can't resolve variable //'CreateToolhelp32Snapshot'

I'm trying to include these files like this:

include_directories(C:\\Program Files\\mingw-w64\\x86_64-7.3.0-posix-seh-rt_v5-rev0\\mingw64\\x86_64-w64-mingw32\\include) #в этой папке tlhelp32.h

add_executable(untitled ...  tlhelp32.h)

Does not exceed. Please tell me how best to do it right

Answer 1

Isn't
it necessary through?
If I remember the pluses correctly, then in quotes we write the path relative to the current compilation unit.

Answer 2

The first thing that catches your eye is the presence of spaces in the path to the folder. Try putting it in quotes:
About the correctness:
Generally speaking, the use of include_directories is considered bad manners and the structure of modern CMake should be based on targets and properties. Your description lacks a bit of data to understand what you want to get. It would be nice if you could provide the full CMake code and describe what you are trying to get.
