No changes in testflight libraries and Xcode 5 now says "ld: library not found for -lTestFlight"

Question

I've been creating some app for some months, and suddently Xcode 5 doesn't want to build it. It just complains with the following error.

Ld build/Debug-iphonesimulator/appname.app/appname normal i386
cd /Users/myname/proyectos/appname/dev/iOS/appname

ld: library not found for -lTestFlight
clang: error: linker command failed with exit code 1 (use -v to see invocation)

If I understand it ok, it complains about testflight, but I haven't changed anything about it in weeks. It compiled it perfectly.

I have to say I've tried adding Adobe ADMS tracking library onto the project (but then undoing its addition). And then after that, linker errors appear.

Any hint? I'm COMPLETELY at lost and frustrated. Are my project files corrupt maybe? (Let's hope not!!) Any hope to recover them in such case?

Greetings

"Problem solved".

Apparently it seemed (as ahwulf said, and I suspected) that my Project paths/libraries/headers where somehow corrupt inside Xcode 5.

What was my solution? After more additional tests, I just physically removed some of my apparently conflicting libraries (testflight, flurry, etc...) from the project (and ALSO from disk) and started compiling, waiting for the obvious compilation errors that would appear.

When they appeared, I just re-added the files XCode asked me to add (one file/library at a time), and then one by one, all these errors started to slowly disappear. My original linking error ALSO disappeared, so my project builds again.

I have the feeling I don't really know what I did, but "it worked".
