Question

我正在尝试将此C++ GitHub repo编译到我的android studio项目中。我将它作为外部C ++库添加到我的项目中，并且可以编译并运行CMake构建;但是，如果我尝试将Java绑定依赖项"-DDNP3_JAVA=ON"作为参数添加到CMake中，则在尝试运行make project和build APK(s)时会出现编译错误。

这是我的build.gradle

android {
    defaultConfig {
        . . . 
        externalNativeBuild {
            cmake {
                arguments "-DDNP3_JAVA=ON" // This is the argument that casues the build to fail
            }
        }
    }
    . . . 
    externalNativeBuild {
        cmake {
            path '../../../../../dnp3/CMakeLists.txt'
        }
    }
}

dependencies {
    . . .
}

这是构建失败时得到的输出。我不确定为什么它会在控制台中重复两次。

Build command failed.

Open File链接到Android的SDK文件夹中FindPackageHandleStandardArgs.cmake的第147行。

macro(_FPHSA_FAILURE_MESSAGE _msg)
    if (${_NAME}_FIND_REQUIRED)    // Throws error to this line
        message(FATAL_ERROR "${_msg}")
    else ()
        if (NOT ${_NAME}_FIND_QUIETLY)
            message(STATUS "${_msg}")
        endif ()
     endif ()
endmacro()

以下是CMakeOutput.log

我已经尝试将我的JAVAHOME系统变量设置为以下4个文件夹，但我得到了相同的错误。

jdk1.8.0_121
JDK-10.0.1
jre1.8.0_121
JRE-10.0.1

我也尝试在虚拟64位Ubuntu系统上运行它，但得到相同的结果
