equivalent for --plat-name flag in build

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: windows 10
• Poetry version: 1.1.8
• Link of a Gist with the contents of your pyproject.toml file:

[tool.poetry]
name = "drr_generator"
version = "0.1.0"
description = ""
authors = ["Elazar <elazar@rsipvision.com>"]
build = "build.py"
exclude = ["./drr_generator"]  # so it won't duplicate the files in the wheel. probably not the correct solution, but can't figure it out for now.

[tool.poetry.dependencies]
python = "^3.7"
numpy = "^1.20.2"

[tool.poetry.dev-dependencies]
pybind11-stubgen = "^0.8.7" # should not be here but poetry has bug of not installing from dev-dependencies. see https://github.com/python-poetry/poetry/issues/2789

[build-system]
requires = ["poetry-core>=1.0.0", "wheel", "pybind11-stubgen"]
build-backend = "poetry.core.masonry.api"

Issue

Not sure if it's a bug or a feature request.

When using poetry build, the resulted artifact is named dist\drr_generator-0.1.0-cp38-cp38-win32.whl. The problem is with the win32 part. it make it impossible to install on python3.8 64bit version, as it fails with:

ERROR: drr_generator-0.1.0-cp38-cp38-win32.whl is not a supported wheel on this platform.

I'm building with a 64bit version of python. When using python setup.py we can have the flag --plat-name=win-amd64 to generate the wheel with the correct name.
I was thinking that the default behavior is to keep the name to be compatible with the python I'm using for the compilation.

I noticed that in python 3.7 it actually give the correct name: dist\drr_generator-0.1.0-cp37-cp37m-win_amd64.whl

Thanks

Start by reproducing the issue with the supplied pyproject.toml on a 64-bit Windows Python environment and run poetry build. Compare the generated wheel tag with the expected win_amd64 tag and the behavior of setup.py --plat-name=win-amd64; done means the artifact is correctly named and installable on the matching Python platform.
