To what environment variable will an administrator assign or append a value if the administrator needs to tell the dynamic linker to look in a build directory for some of a program's shared libraries?

`LD_LOAD_PATH` is not a standard environment variable used by the dynamic linker for specifying library search paths.

`LD_LIB_PATH` is not a standard environment variable used for this purpose by the dynamic linker, though it might be confused with the correct variable.

The `LD_LIBRARY_PATH` environment variable provides a colon-separated list of directories that the dynamic linker (e.g., `ld.so` on Linux) searches for shared libraries before looking in standard system locations. This is extremely useful for developers to test programs with custom-built libraries located in a build directory without installing them system-wide.

`LD_SHARE_PATH` is not a standard environment variable used by the dynamic linker for shared library search paths.

`LD_RUN_PATH` is a historical term or a conceptual path embedded in executables (often via RPATH during compilation) but not a runtime environment variable the dynamic linker uses in the same way as `LD_LIBRARY_PATH`.
