I am on the latest stable Poetry version, installed using a recommended method.

Issue
In my pyproject.toml I have
[tool.poetry.build]
script = "build.py"
generate-setup-file = false
[build-system]
requires = ["poetry-core", "protoc-exe"]
build-backend = "poetry.core.masonry.api"
and my build.py invokes the protoc command, which is provided by the protoc-exe module, listed in [build-system].
This works fine with poetry install --sync:
% poetry install --sync
Installing dependencies from lock file
Preparing build environment with build-system requirements poetry-core, protoc-exe
Installing the current project: mypoetrytest (0.1.0)
But it fails with poetry build:
% poetry build
Preparing build environment with build-system requirements poetry-core, protoc-exe
Building mypoetrytest (0.1.0)

In the case of poetry build, the command protoc is in the bin directory of the virtualenv, but the bin directory is not added to the PATH environment variable.
Setting generate-setup-file = true does not help.
