对于s390x的rhel发行版构建doxygen v1.8.15时，“make docs”失败了

Question

“make docs”在构建doxygen v1.8.15 for rhel和sles发行版s390x时失败了。

使用“doxygen-latex”v1.8.5包装为rhel安装胶乳

bash-4.2$ make docs VERBOSE=1

任何关于上述错误的指针都会有所帮助。

来自CMake的旧文档：https://cmake.org/cmake/help/v2.8.12/cmake.html

我知道了

-E：CMake命令模式。

为了实现真正的平台独立性，CMake提供了可在所有系统上使用的命令列表。使用-E help运行使用信息。可用的命令有：chdir，compare_files，copy，copy_directory，copy_if_different，echo，echo_append，environment，make_directory，md5sum，remove，remove_directory，rename，tar，time，touch，touch_nocreate。此外，还提供了一些特定于平台的命令。在Windows上：comspec，delete_regv，write_regv。在UNIX上：create_symlink。

因此使用的CMake版本已经过时了。看起来，对于-E env，至少需要3.1。

编辑：

关于最小使用版本：我刚刚将一个提议的补丁推送到github（pull request 6771，https://github.com/doxygen/doxygen/pull/6771）。

编辑2：pul请求的代码已经集成在github上的master中。
