Henry Schreiner a49c4dbfa4 chore(cmake): carry option-driven defines on pybind11_headers INTERFACE (#6130)
* chore(cmake): carry option-driven defines on pybind11_headers INTERFACE

PYBIND11_DISABLE_HANDLE_TYPE_NAME_DEFAULT_IMPLEMENTATION and
PYBIND11_SIMPLE_GIL_MANAGEMENT were directory-scoped
add_compile_definitions, which only reached the master-project test
build. On the pybind11_headers INTERFACE (like
PYBIND11_INTERNALS_VERSION) they also apply in add_subdirectory mode
and in the exported/installed targets.

Assisted-by: ClaudeCode:claude-fable-5

* test(cmake): verify option-driven defines reach consumer targets

Extend subdirectory_target and installed_target to check that
PYBIND11_DISABLE_HANDLE_TYPE_NAME_DEFAULT_IMPLEMENTATION and
PYBIND11_SIMPLE_GIL_MANAGEMENT propagate through the pybind11_headers
usage requirements. Fails without the parent commit.

baa540ec34 fix: support free-threaded CPython with GIL disabled (#5148)
* Support free-threaded CPython (PEP 703)

Some additional locking is added in the free-threaded build when
`Py_GIL_DISABLED` is defined:

- Most accesses to internals are protected by a single mutex
- The registered_instances uses a striped lock to improve concurrency

Pybind11 modules can indicate support for running with the GIL disabled
by calling `set_gil_not_used()`.

* refactor: use PYBIND11_MODULE (#11)

Signed-off-by: Henry Schreiner <henryschreineriii@gmail.com>

* Address code review

* Suppress MSVC warning

* Changes from review

* style: pre-commit fixes

* `py::mod_gil_not_used()` suggestion.

* Update include/pybind11/pybind11.h

Dean Moldovan 443ab5946b Replace PYBIND11_PLUGIN with PYBIND11_MODULE
This commit also adds `doc()` to `object_api` as a shortcut for the
`attr("__doc__")` accessor.

The module macro changes from:
```c++
PYBIND11_PLUGIN(example) {
    pybind11::module m("example", "pybind11 example plugin");
    m.def("add", [](int a, int b) { return a + b; });
    return m.ptr();
}
```

to:

```c++
PYBIND11_MODULE(example, m) {
    m.doc() = "pybind11 example plugin";
    m.def("add", [](int a, int b) { return a + b; });
}
```

Using the old macro results in a deprecation warning. The warning
actually points to the `pybind11_init` function (since attributes
don't bind to macros), but the message should be quite clear:
"PYBIND11_PLUGIN is deprecated, use PYBIND11_MODULE".

Dean Moldovan b0f3885c95 Make sure add_subdirectory and find_package behave identically
Add a BUILD_INTERFACE and a pybind11::pybind11 alias for the interface
library to match the installed target.

Add new cmake tests for add_subdirectory and consolidates the
.cpp and .py files needed for the cmake build tests:

Before:
tests
|-- test_installed_module
|   |-- CMakeLists.txt
|   |-- main.cpp
|   \-- test.py
\-- test_installed_target
    |-- CMakeLists.txt
    |-- main.cpp
    \-- test.py

After:
tests
\-- test_cmake_build
    |-- installed_module/CMakeLists.txt
    |-- installed_target/CMakeLists.txt
    |-- subdirectory_module/CMakeLists.txt
    |-- subdirectory_target/CMakeLists.txt
    |-- main.cpp
    \-- test.py
