Problem

I've upgraded to using libgit2 v1.9, and I've been getting build errors that weren't there previously. This is caused by the custom<stdint.h> header file.

The build errors only occur when using ainstalled libgit2.
I am using Fedora Linux 41.

Example usage code

CMakeLists.txt

cmake_minimum_required(VERSION3.30)project(using_libgit2)add_executable(my_exemain.cpp)find_package(libgit2)target_link_libraries(my_exePRIVATElibgit2::libgit2package)

main.cpp

#include<cstdint>intmain() {return0;}

Trying to build this leads to errors like this:

/usr/include/c++/14/cstdint:51:11: error: ‘int8_t’ has not been declared in ‘::’   51 |   using ::int8_t;

Explanation

When using the installed libgit2 the include paths will now containinclude/git2 instead ofinclude. This is problematic because there's a custom<stdint.h> in thegit2 folder.
Now any user code that has#include <stdint.h>, will now include the custom<stdint.h> header instead of the standard one. Which causes the build error.

Solution

This PR fixes this regression.
