Thats not correct. Runtime loading of libraries depends on the runtime linker
used, which is ld on Linux usually. And that one finds libraries by
checking its ld.so.conf, the LD_LIBRARY_PATH and a possibly-existing
RPATH/RUNPATH setting in the executable. On Windows the runtime-linker
looks through the PATH variable, in the directory where the executable
is and at a few system-places.

What you might refer to is CMake's support for RPATH/RUNPATH on Linux,
but this can be turned off, tuned so the path is relative to the
executable and the linker simply ignores that if it cannot find a
library at the specified place and falls back to the other two options.
