TARGET_ROOT_OUT
时间: 2023-09-19 15:09:56 浏览: 63
TARGET_ROOT_OUT 是指在 Android 编译过程中,输出的目标文件夹路径,即编译后的目标设备的根目录。它的值可以通过以下公式计算得到:PROUDCT_OUT = out/target/product/xxx/$(TARGET_COPY_OUT_ROOT) ,其中 xxx 是目标设备的名称,TARGET_COPY_OUT_ROOT 是 root 文件系统的路径。而 PROUDCT_OUT 则是指最终的输出目录。所以可以得到 TARGET_ROOT_OUT = out/target/product/xxx/root/ 。

在您的 CMakeLists.txt 文件中,将 `target_link_libraries()` 指令添加到 `add_subdirectory("${_out}")` 的下方。具体位置如下所示:
```cmake
...
# include catkin from workspace or via find_package()
if(_res EQUAL 0)
set(catkin_EXTRAS_DIR "${CMAKE_SOURCE_DIR}/${_out}/cmake")
# include all.cmake without add_subdirectory to let it operate in same scope
include(${catkin_EXTRAS_DIR}/all.cmake NO_POLICY_SCOPE)
add_subdirectory("${_out}")
# Add the target_link_libraries() here
target_link_libraries(your_target_name avcodec avformat swscale)
else
# use either CMAKE_PREFIX_PATH explicitly passed to CMake as a command line argument
# or CMAKE_PREFIX_PATH from the environment
if(NOT DEFINED CMAKE_PREFIX_PATH)
if(NOT "$ENV{CMAKE_PREFIX_PATH}" STREQUAL "")
if(NOT WIN32)
string(REPLACE ":" ";" CMAKE_PREFIX_PATH $ENV{CMAKE_PREFIX_PATH})
else()
set(CMAKE_PREFIX_PATH $ENV{CMAKE_PREFIX_PATH})
endif()
endif()
endif()
...
endif()
...
```
请注意将 `your_target_name` 替换为您实际的目标名称。这将在生成目标时链接 avcodec、avformat 和 swscale 库。
