【Delphi】RAD 10.4 开发Android时如何在迁移SDK和NDK路径后解决提示 ld: cannot find -lxxx的问题

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 usrlib 路径仍然是C盘的，如下：

dccaarm command line for "Project1.dpr"
  f:program_filesembarcaderostudio21.0indccaarm.exe -$O- --no-config -B -Q -TX.so -AGenerics.Collections=System.Generics.Collections;
  Generics.Defaults=System.Generics.Defaults -DDEBUG -E.AndroidDebug -If:program_filesembarcaderostudio21.0libAndroiddebug;
  f:program_filesembarcaderostudio21.0libAndroidRelease -LEC:UsersPublicDocumentsEmbarcaderoStudio21.0BplAndroid 
  -LNC:UsersPublicDocumentsEmbarcaderoStudio21.0DcpAndroid -NU.AndroidDebug -NSSystem;Xml;Data;Datasnap;Web;Soap; 
  -Of:program_filesembarcaderostudio21.0libAndroidRelease -Rf:program_filesembarcaderostudio21.0libAndroidRelease 
  -Uf:program_filesembarcaderostudio21.0libAndroiddebug;f:program_filesembarcaderostudio21.0libAndroidRelease 
  --libpath:C:UsersPublicDocumentsEmbarcaderoStudio21.0PlatformSDKsandroid-ndk-r21sourcescxx-stlllvm-libc++libsarmeabi-v7a;
  C:UsersPublicDocumentsEmbarcaderoStudio21.0PlatformSDKsandroid-ndk-r21platformsandroid-23arch-armusrlib 
  --linker:F:Program_FilesEmbarcaderoStudio21.0PlatformSDKsandroid-ndk-r21	oolchainsarm-linux-androideabi-4.9prebuiltwindows-x86_64inarm-linux-androideabi-ld.exe 
  -V -VN -NO.AndroidDebug  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：

注意其中的<DelphiNDKLibraryPath>仍然指向未迁移前的C盘路径，因此将该路径修改后，再重新使用import功能导入设置即可。
