CMake找不到JNI

Question

我创建了一个具有C ++支持的新Android Studio项目，但没有添加任何内容。该项目使用CMake构建，编译和运行。然后CMakeLists.txt，我在文件底部添加了以下两行代码，并收到CMake构建错误。

find_package(Java COMPONENTS Development)       # Line 47

find_package(JNI REQUIRED)                      # Line 48

这是我在构建项目时遇到的错误

-- Found Java: /usr/lib/jvm/java-10-oracle/bin/java (found version "10.0.1") found components:  Development 

-- Configuring incomplete, errors occurred!

CMake在从命令行调用时运行，但是由于某种原因在Android Studio中失败，我不确定为什么。
