BoostDetectToolset-1.90.0.cmake file not found in an include() call in boost_python-config.cmake

I first installed Python 3.14, Boost 1.90.0 and Boost.Python with Brew on my macOS Sonoma 14.4 and built a minimum working example with CMake, but it didn't work.

When I used
```cmake
find_package(Boost REQUIRED COMPONENTS python)
```
to find Boost and ran with command
```bash
cmake .. -DCMAKE_PREFIX_PATH='/usr/local/opt/boost' -DBoost_DEBUG=1
```
the following error occured:
```
CMake Error at /usr/local/lib/cmake/boost_python-1.90.0/boost_python-config.cmake:29 (include):
include could not find requested file:

/usr/local/lib/cmake/boost_python-1.90.0/../BoostDetectToolset-1.90.0.cmake
Call Stack (most recent call first):
/usr/local/opt/boost/lib/cmake/Boost-1.90.0/BoostConfig.cmake:141 (find_package)
/usr/local/opt/boost/lib/cmake/Boost-1.90.0/BoostConfig.cmake:262 (boost_find_component)
CMakeLists.txt:10 (find_package)
```

After checking the file system, no file named `BoostDetectToolset-1.90.0.cmake` was found in either `/usr/local/lib/cmake/boost_python-1.90.0/..`, `/usr/local/opt/boost-python3/lib/cmake`, or `/usr/local/Cellar/boost-python3/1.90.0/lib/cmake`. The only `BoostDetectToolset-1.90.0.cmake` file was in `/usr/local/Cellar/boost/1.90.0_1/lib/cmake`.

Because there is a
```cmake
include(${CMAKE_CURRENT_LIST_DIR}/../BoostDetectToolset-1.90.0.cmake)
```
in the file `/usr/local/lib/cmake/boost_python-1.90.0/boost_python-config.cmake` which was auto-generated by Boost, and `CMAKE_CURRENT_LIST_DIR` here refers to `/usr/local/lib/cmake/boost_python-config.cmake`, I suppose there must be something wrong with the generator of the file.

The following are my minimum working example:
[CMakeLists.txt](https://github.com/user-attachments/files/30335425/CMakeLists.txt)
[module.cpp](https://github.com/user-attachments/files/30335426/module.cpp)

Do you have any suggestions? Thanks in advance.

使用所述的 Boost 和 Python 版本執行隨附的 CMakeLists.txt 範例，然後檢查失敗的 include() 呼叫附近的 boost_python-config.cmake 和 BoostConfig.cmake。將產生的設定路徑與 issue 中回報的 BoostDetectToolset-1.90.0.cmake 位置進行比較；當 find_package(Boost REQUIRED COMPONENTS python) 成功完成時，即表示完成。
