How to check which toolchain is used?

[qudix]

Is there a way to check if a target is using a specific toolchain?

For example, only add certain flags if not using clang-cl:

on_config(function(target)
    ....
    if target:is_plat("windows") then
        target:add("cxxflags", "/permissive-")
        if not target_using_clang_cl then
            target:add("cxxflags", "/Zc:externConstexpr")
        end
    end
    ....
end)

if target:has_tool("cxx", "clang", "clangxx") then

This seems to work:

if not a_target:has_tool("cxx", "clang_cl") then
