【问题描述】：
我正在按照此处的说明设置 OpenCV 以进行 Java 开发。 http://docs.opencv.org/trunk/doc/tutorials/introduction/desktop_java/java_dev_intro.html。 我正在使用带有 Java 1.8.0_25 的 Mac OS X 10.10.1。
我无法使用 cmake 将 Java 添加到“待构建”列表中，这是创建 Java 开发所需的与 Java 链接的本机库和 jar 文件的先决条件。
我收到的警告如下。我不知道如何解释此输出，也不知道是否需要对警告做出响应。错误中没有提到 Java。任何人都可以帮助我超越这个阶段吗？
[注意：我在 OpenCV 论坛上问过这个问题，但没有得到回复。]
