    \ingroup list-of-items
    \keyword QML.BinaryProbe
    \inherits PathProbe

    \brief Locates executable files outside the project.

    Finds executable files that have the specified file names.

    BinaryProbe searches for executable files within directories specified by the PATH environment
    variable.

    \note On Unix, also searches in the \c /usr/bin and \c /usr/local/bin directories by default.
    Override \l {PathProbe::platformSearchPaths}{PathProbe.platformSearchPaths} to change this
    behavior.

    \note On Windows, only files that have \e .com, \e .exe, \e .bat, \e .cmd extensions are
    considered \e executables. Override \l {PathProbe::nameSuffixes}{PathProbe.nameSuffixes} to
    change this behavior.

    For example, BinaryProbe can be used to search for a protobuf compiler executable as follows:

    \code
    import qbs.File
    import qbs.Probes

    Module {
        // search for a protoc executable
        Probes.BinaryProbe {
            id: protocProbe
            names: "protoc"
        }
        property string executableFilePath: protocProbe.filePath

        validate: {
            if (!File.exists(executableFilePath))
                throw "The executable '" + executableFilePath + "' does not exist.";
        }

        // use the found executable
        Rule {
            // rule input/outputs here...

            // run executable
            prepare: {
                var args = // initialize arguments...
                var cmd = new Command(executableFilePath, args);
                cmd.highlight = "codegen";
                cmd.description = "generating protobuf files for " + input.fileName;
                return [cmd];
            }
        }
    }
    \endcode
