VS2026 Support in BoostDetectToolset.cmake

[SSimboeckMesu]

Visual Studio 2026 is not handled in BoostDetectToolset.cmake.

line 99:

  if((MSVC_VERSION GREATER 1929) AND (MSVC_VERSION LESS 1950))

    set(BOOST_DETECTED_TOOLSET "vc143")

  elseif((MSVC_VERSION GREATER 1919) AND (MSVC_VERSION LESS 1930))

You would need something like:

  if((MSVC_VERSION GREATER 1949) AND (MSVC_VERSION LESS ????))

    set(BOOST_DETECTED_TOOLSET "vc145")

  elseif((MSVC_VERSION GREATER 1929) AND (MSVC_VERSION LESS 1950))

    set(BOOST_DETECTED_TOOLSET "vc143")

But what should be the maximum?
If this is clarified, I could make the pull request.

The maximum should be assumed to be 1960 for now; if Microsoft exceed it (as they did for 14.3), we'll bump it then.
