Mailcore2“ld:在构建时未找到-licudata的库”。

I've got a project which has been building fine using Mailcore2. I opened the project today and received errors along the lines of "SDK not found" during the Mailcore2 shell script. I discovered that I needed to rename .m files which import MailCore.h to .mm. I am now receiving the error "ld: library not found for -licudata" when building. This error is displayed within my target. My target's linker flags are as follows:I've got a project which has been building fine
