【Delphi】RAD10.4开发Android时如何在迁移SDK和NDK路径后解决提示ld:cannotfind-lxxx ...

今天使用lite版本安装了RAD Delphi10.4，发现自动把Android的SDK和NDK目录安装到C盘下，由于C盘容量紧张，所以想把目录迁移到其他路径！

在之前的版本是直接移动目录，在到delphi的tools-options菜单页面中修改SDK路径即可。

但是这次修改后发现在link时仍然找不到路径，查看了delphi的编译命令行信息，发现其中 usr\lib 路径仍然是C盘的，如下：

dccaarm command line for "Project1.dpr"
  f:\program_files\embarcadero\studio\21.0\bin\dccaarm.exe -$O- --no-config -B -Q -TX.so -AGenerics.Collections=System.Generics.Collections;
  Generics.Defaults=System.Generics.Defaults -DDEBUG -E.\Android\Debug -If:\program_files\embarcadero\studio\21.0\lib\Android\debug;
  f:\program_files\embarcadero\studio\21.0\lib\Android\Release -LEC:\Users\Public\Documents\Embarcadero\Studio\21.0\Bpl\Android 
  -LNC:\Users\Public\Documents\Embarcadero\Studio\21.0\Dcp\Android -NU.\Android\Debug -NSSystem;Xml;Data;Datasnap;Web;Soap; 
  -Of:\program_files\embarcadero\studio\21.0\lib\Android\Release -Rf:\program_files\embarcadero\studio\21.0\lib\Android\Release 
  -Uf:\program_files\embarcadero\studio\21.0\lib\Android\debug;f:\program_files\embarcadero\studio\21.0\lib\Android\Release 
  --libpath:C:\Users\Public\Documents\Embarcadero\Studio\21.0\PlatformSDKs\android-ndk-r21\sources\cxx-stl\llvm-libc++\libs\armeabi-v7a;
  C:\Users\Public\Documents\Embarcadero\Studio\21.0\PlatformSDKs\android-ndk-r21\platforms\android-23\arch-arm\usr\lib 
  --linker:F:\Program_Files\Embarcadero\Studio\21.0\PlatformSDKs\android-ndk-r21\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ld.exe 
  -V -VN -NO.\Android\Debug  Project1.dpr

再次检查sdk路径，发现并无错误，猜测可能是delphi的bug，估计是漏掉了NDK library Path，页面中仅有C++ Builder的NDK library Path设置项（难道是lite版本裁剪后导致的？）。

好在发现delphi提供了设置项的export和import功能，因此，我先使用export导出设置文件，内容如下：
