Qt6第二个LTS出来了，周日找时间安装并测试了Qt6.5LTS，安装我是按我之前的一个博客记录来做的，用的是国内境像，顺利快速安装完成，下面是设置的过程关键总结。

 一、Devices

Android设备(Device)选择

二、Kits

（一）新机(64位系统)选arm64-v8a，性能优，不要选v7a，性能会低。

“专门针对下“SDK Manager"注解下

 

（二）Android Qt 工具链设置

 

三、xxx.cmake

（1）如果提示下面错误(cmake过程出现)

问题: C:\Qt6_5LTS\6.5.1\android_arm64_v8a\lib\cmake\Qt6BuildInternals\QtBuildInternalsExtra.cmake:45: error: Syntax error in cmake code at C:/Qt6_5LTS/6.5.1/android_arm64_v8a/lib/cmake/Qt6BuildInternals/QtBuildInternalsExtra.cmake:45 when parsing string C:\Qt6_5LTS Invalid character escape '\Q'. C:/Qt6_5LTS/6.5.1/android_arm64_v8a/lib/cmake/Qt6BuildInternals/Qt6BuildInternalsConfig.cmake:54 (include) C:/Qt6_5LTS/6.5.1/android_arm64_v8a/lib/cmake/Qt6/Qt6Config.cmake:157 (find_package) CMakeLists.txt:14 (find_package)
思考：
根据提示进入“QtBuildInternalsExtra.cmake”，观察“:\Qt6_5LTS”，对比同一文件中的路径，怀疑是“转义符问题造成”。下面蓝色字体为实际xxx.cmake文件的摘录
if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT AND
        NOT QT_BUILD_INTERNALS_NO_FORCE_SET_INSTALL_PREFIX
        AND NOT QT_SUPERBUILD)
    set(qtbi_orig_prefix "C:\Qt6_5LTS")
    set(qtbi_orig_staging_prefix "C:/Qt6_5LTS/6.5.1/android_arm64_v8a")
尝试（qPass):
把"\",改为“/”，问题解决；也即：set(qtbi_orig_prefix "C:/Qt6_5LTS")
