[libigl:x64-windows] can't compile canonical example due to missing header.

[volumeDigital]

Describe the bug

Installation of libigl not sufficient to compile the canonical libigl example.

Many headers from libigl don't appear to be installed, including igl/opengl/glfw/Viewer.h

Environment

• OS: Windows 10 Pro 22H2 19045.2846
• Compiler: Microsoft (R) C/C++ Optimizing Compiler Version 19.35.32217.1 for x64

To Reproduce

1. vcpkg install libigl[*]
2. Create blank C++ project using Microsoft Visual Studio Community 2022 (64-bit) - Current Version 17.5.4
3. Create a main.cpp with

#include <igl/opengl/glfw/Viewer.h>

int main(int argc, char* argv[])
{
	return 0;
}

5. Attempt to build

Expected behavior

Build to succeed.

Failure logs
Error C1083 Cannot open include file: 'igl/opengl/glfw/Viewer.h': No such file or directory

Additional context

• Have enabled integrations, they work fine for other packages (Eigen/raylib)
• Also tried for x86-windows, same problem.

Rolled back to #475954aaa (last commit using libigl 2.3.0, and just before 2.4.0 is introduced) and installed only with opengl and glfw features -> Viewer.h is installed as expected, and code above compiles.

The commit that introduces 2.4.0 (3fce2d) isn't currently buildable, as it predates PR #30546

Adjusting to use msys2-runtime-3.2.0-15 - which is still available on mirror - makes 3fce2d buildable.

Once built, we can see Viewer.h is not installed, and so this is the commit that introduces the issue.

Use manifest mode, or use a copy of the old port version as overlay port.

This is because the upstream does not provide the Viewer.h header file after version 2.4.0, please use this port as suggested by dg0yt.
