Add support for building IfcOpenShell library

[MugundanMCW]

PR Description:

• The PR adds support for building the IfcOpenShell library for both Windows x64 and Windows ARM64 as part of the FreeCAD LibPack compilation process.

• The build_ifcopenshell function handles the building of dependencies, the IfcOpenShell Python extension, and installs IfcOpenShell into the FreeCAD LibPack installation directory.

• The changes have been validated on both Windows x64 and Windows ARM64 platforms to ensure proper functionality of IfcOpenShell with FreeCAD

The looks clean and correct to me. How can I help get this integrated?

[chennes]

It isn't working for me (in a non-ARM x64 system). It just seems to sit there doing nothing after the "Building ifcopenshell" standard printout. This is very different from the others, since it's using a custom wrapper around the CMake calls, so it's taking me some time to get my head around what's going on.

Hi @chennes
Did you encounter any build errors while building IfcOpenShell on Windows x64?

[chennes]

I'm peeling back the onion now. The first problem is that:

subprocess.run(
                [self.init_script, "&", build_deps_cmd, vs_platform, build_cfg],
                check=True,
                capture_output=True,
                env=env,
                cwd=win_dir,
            )

doesn't work as expected: the build-deps.cmd script has a confirmation prompt, so the reason that my build just sat there was because that script was waiting for user input.

Second, when I run that script by hand, it tells me I have to be using PowerShell, which isn't how the automated system is configured, so that needs to be resolved somehow. And then, once I do am running in PowerShell, building the proj dependency fails with a linker error, unable to find some sqlite3 functions like sqlite3_close and sqlite3_exec. This may or may not be related to the warning:

The first two problems were easy enough to resolve (and even resulted in an improved process -- I didn't know about the vswhere command). Onto the third...

[chennes]

OK -- simply deleting the ifcopenshell clone and letting it re-run with the updated Visual Studio configuration script got me through the dependencies builds (though it's pretty awful that we have to rebuild so many dependencies - I assume that you tried to build IfcOpenShell with the already-built HDF5, OCCT, etc. and it didn't work?).

Anyway, my IfcOpenShell CMake call is now failing with:

  The source directory

    G:/FreeCAD/FreeCAD-LibPack-chennes/working/ifcopenshell/src/svgfill

  does not contain a CMakeLists.txt file.

[chennes]

And that problem anyway turned out to be related to how git submodules work (or fail to work, as the case may be). Next up...

If I manually run each step on the command line it eventually works, and I can backtrack and run the script to get all the copying done, but I have yet to be able to get the script to run on its own from start to finish.

[chennes]

I've incorporated these commits into a new PR that updates most of the rest of the LibPack as well, and takes some steps towards getting the IfcOpenShell build working in the context of the script. Still a work-in-progress, it doesn't run cleanly yet. #63
