我按照此处的说明设置OpenCV for Java开发。 http://docs.opencv.org/trunk/doc/tutorials/introduction/desktop_java/java_dev_intro.html。 我使用Mac OS X 10.10.1和Java 1.8.0_25。
我无法将Java添加到＆＃34;要构建＆＃34; list使用cmake，这是创建Java开发所需的Java链接本机库和jar文件的先决条件。
我得到的警告如下。我不知道如何解释这个输出，我不明白我是否需要回应警告。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，但没有得到答复。]
