qcaml.0.1.4

Experimental OCaml library for quantum computing simulation
QCaml is a lightweight OCaml library for experimenting with quantum states,
gates and measurements. It provides tools for learning quantum computing
concepts and visualizing qubit states on the Bloch sphere.

Features:

• Single qubit state representation with complex amplitudes
• Fundamental quantum gates (Hadamard, Pauli-X/Y/Z)
• Quantum measurements with probabilistic state collapse
• Interactive Bloch sphere visualization using OpenGL/GLUT
• Comprehensive test suite

OK, this is now down to

• a Cygwin MinGW failure
  • the paths are slightly different there https://www.cygwin.com/packages/noarch/mingw64-x86_64-freeglut/mingw64-x86_64-freeglut-2.8.1-1 (and the older version available doesn't include a .pc-file for pkg-config)
• an Arch failure, which I understand as an Arch packaging failure. From the below error it seems including glut.h includes freeglut_std.h which needs GL/glu.h - however that isn't installed, so it seems a dependency on the glu package https://archlinux.pkgs.org/rolling/archlinux-extra-x86_64/glu-9.0.3-2-x86_64.pkg.tar.zst.html is missing in Arch's freeglut package 🤔

As I am a GL novice, @Leonidas-from-XIV what do you think?

Otherwise, this LGTM - thanks for your effort!

@jmid That's a good investigation and I concur. freeglut lists glu as make dependency (which I assume to be a equivalent to a build dependency in OPAM terms), but looking at glut.h, line 198 it seems like everyone using glut.h will also need glu.h which thus needs to be installed.

I'll try to create an account in the Arch Linux bug tracker and file it there.

Okay, great! Thank you for the reviews :))

I'll try to create an account in the Arch Linux bug tracker and file it there.

I've created a ticket here, but I have a suspicion that it might be an issue on our side, as glu is a makedepend and from what I understand we should probably install makedepends when trying to build packages that depend on these libraries.

Thank you for your feedback, I will try to add makedepends this evening and see what happens 👍🏻
