This adds Google/Filament

This is a successor of #17369

The linker fails to find some of the libraries although their targets are linked in CMake. Any clue why this happens?

I don't see any -L flags.

Maybe the "targets" are not targets where they are used? They are not namespaced, so you don't get good diagnostics. Try using the GLOBAL option to find_package.

Thanks, I added GLOBAL and it fixed the issue!

Thanks for the feedback. Taken as an example to https://gitlab.kitware.com/cmake/cmake/-/issues/25866.

It seems all the build system issues are resolved. Now, I am hitting some linker errors because of the differences between how Filament uses its vendored Glslang, spirv, civetweb, etc.

Now, I am hitting some linker errors because of the differences between how Filament uses its vendored Glslang, spirv, civetweb, etc.

Maybe that's a good intermediate result? Without de-vendoring, such issues might be offloaded to the users of vpckg ports...

Yes, it's a good progress. However, the issue is happening because of de-vendoring. They use custom CMake for glslang, spirv, civetweb, and the versions they use are different from the vcpkg versions.

I tried with GCC, and I get a similar error. Inside the CI, there are other errors that must be resolved.

Got a successful build with Clang on Linux! 🎉

Update portfile.cmake

Update filament.json

aminya · 2024-11-07T09:02:05Z

Getting Filament to build with gcc is too much work. There are numerous compiler errors that need to be resolved, which is out of the scope of this PR. I have added the clang requirement in the port for Linux.

dg0yt · 2024-11-07T11:50:12Z

ports/filament/portfile.cmake

+    vcpkg_find_acquire_program(CLANG)
+    set(COMPILER -DCMAKE_CXX_COMPILER=${CLANG}++ -DCMAKE_C_COMPILER=${CLANG})


Ports must not change the compiler like this.
CI can expect it to fail via scripts/ci.baseline.txt.

The portfile can print a message. (If you want a conditional message, you could vcpkg_cmake_get_vars.)

Why not? Ports can have compiler requirements, and this line declares that. I patched the original CMake not to error on gcc, but if vcpkg is against that, I will revert that patch. The compilation fails with gcc towards the ends. It is quite wasteful not to error out early and let the users know about the clang requirement.
I'd either keep the original requirement in CMakeLists.txt or here in vcpkg.

Another benefit of keeping this in vcpkg is that we can build filament with clang but link to it from gcc. Not having this, forces the users to use Clang for everything!

The toolchain - including compiler - is controlled by the triplet. Users may use per-port customization in triplet files.

To error out early, use vcpkg_cmake_get_vars to get toolchain information.

What about using gcc with clang built Filament? Not having this makes it unnecessarily hard.

dg0yt · 2024-11-08T08:44:35Z

The CMake config package is not provided by upstream. So the package name must be unofficial-filament, the target namespace must be unofficial::filament::, and the config installation dir must be changed accordingly.
