Delphi XE5 is designed for Windows 32bit, Windows 64bit, MacOS 32bit, iOS, Android and Web. It is not intended for Windows Mobile.
You can download lazarus from http://www.lazarus.freepascal.org It supports WinCE.
You can upgrade to Delphi 10.1 Berlin or even wait for Delphi 10.2 Godzilla. Delphi 10.1 Berlin Update 2 includes the development of Windows 10 and, therefore, the ability to convert your Win32 or Win64 application to an AppX file. The AppX file is used to run applications on Windows 10. This includes Desktop, Xbox One, HoloLense, Mobile, Tablet, IoT, etc. Although I believe that Delphi 10.1 Berlin Update 2 converts to AppX, uses Microsoft's Desktop Bridge, and thus your converted application may only work on a Windows 10 and Windows 10 desktop computer.
