[Linux] 在 gcc 中使用 rpath/rpath-link 指定 shared library 搜尋路徑

You need to add the dynamic library equivalent of -L: -Wl,-rpath-link,/path/to/lib This will cause the linker to look for shared libraries in non-standard places, but only for the purpose of verifying the link is correct. If you want the program to find the library at that location at run-time, then there's a similar option to do that: -Wl,-rpath,/path/to/lib But, if your program runs fine without this then you don't need it.
