Platform: ubuntu22.04 I'm using cmake to link to a 3rd party library. It looks like:

// Those two files are identical. 
// abc.so is the original file and libabc.so is a copy
${shared}/libabc.so
${shared}/abc.so

My CMakeLists.txt:

LINK_DIRECTORIES(${shared})

ADD_EXECUTABLE(main ...)

TARGET_LINK_LIBRARIES(main libabc.so)

So far it works fine. You may have noticed that I have shared/libabc.so and shared/abc.so at the same time. They are identical. So I delete libabc.so (abc.so is the original file) and create a link file with ln -s shared/abc.so shared/libabc.so. But I got:

/usr/bin/ld: cannot find -labc: No such file or directory
collect2: error: ld returned 1 exit status

Why do I get this error when libabc.so did exists?
