Probably the same logic as for target_link_libraries().
E.g. implicit link directories aren't repeated as explicit link
directories.
But it is not an implicit link directory at least not according to the
output of
"/sbin/ldconfig -p" . What does cmake consider an implicit link directory?
I think a directory in which the linker looks by default (not the
runtime loader; which is what ldconfig manages).
Run e.g.
echo "int main() {}"|/opt/XXX/bin/g++ -xc++ - -v
And see the directories being passed to collect2 with -L.
