    Call the m4 macro PHP_REQUIRE_CXX in your config.m4 then.
    That will check for a C++ compiler and set the appropiate
    variables.

    If you can make sure that no license conflicts emerge, then
    you can do it this way:

    Extract the respective m4 macros from their acinclude.m4
    (or whereever it is stored) and add them to your extension's
    config.m4.
