Is Boost.Python is bound to specific python version? #433

I am trying to understand if Boost.Python has binding for a particular version of Python? I am using Cmake+vcpkg, if I do

find_package(Python COMPONENTS Interpreter Development.Module Development.SABIModule REQUIRED)
find_package(Boost REQUIRED COMPONENTS python${Python_VERSION_MAJOR}${Python_VERSION_MINOR})

and my vcpkg is installing the latest versions of boost-python (1.8.4), then everything works if I have python 3.11. But if I have a different python version, then boost complains that it can't find Python:

-- Found Python: C:\Users\user\AppData\Local\Temp\build-env-tf4blxq2\Scripts\python.exe (found version "3.9.19") found components: Interpreter Development.Module Development.SABIModule

I wonder if this is related to Boost.Python or perhaps this is vcpkg issue, or something else?

boost::python is bound to the version of Python it was built against.
