You can add alternate paths with -L/path.
Look at `perldoc ExtUtils::MakeMaker`:
LIBS
An anonymous array of alternative library specifications to be
searched for (in order) until at least one library is found. E.g.
'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]
Mind, that any element of the array contains a complete set of
arguments for the ld command. So do not specify
'LIBS' => ["-ltcl", "-ltk", "-lX11"]
See ODBM_File/Makefile.PL for an example, where an array is needed. If
you specify a scalar as in
'LIBS' => "-ltcl -ltk -lX11"
MakeMaker will turn it into an array with one element.
Cheers,
