Why do I receive "File corrupted!" error after changing library ID from @rpath to @executable_path?

I use Qt 5.12 with XCode 10 for building my desktop application. I've received a .dylib from a 3rd party in order to integrate it into my application. I've modified my .pro file to add the library in the LIBS variable.

If I leave the library id as @rpath/test.dylib (compatibility version 0.0.0, current version 0.0.0) everything works fine. If I use install_name_tool and change the library id to @executable_path/../Frameworks/test.dylib, I get a weird error after starting my app:

File corrupted! This program has been manipulated and maybe it's infected by a Virus or cracked. This file won't work anymore.

Note: I am sure that the library is available at @executable_path/../Frameworks so that is not the issue.

Is the dylib codesigned? – Siguza Dec 27 '21 at 19:35
I believe not: codesign --verify --deep --verbose test.dylib lib/test.dylib: code object is not signed at all In architecture: x86_64 – Meliodas Dec 28 '21 at 07:52
Then there must be some proprietary mechanism in place to detect tampering. – Siguza Dec 28 '21 at 18:48
