libtool adds an annoying -L/usr/lib in link command

[christian caremoli]

Hello Gary

I resend my question from gmail.

> Most likely your libhdf.la has -L/usr/libs in its dependency_libs entry.  You can fix that by editing the libhdf.la file to pass the library name by its full path, or by adjusting the install process of libhdf not to record -L/usr/libs there.

dependency_libs in libhdf5.la does not contain -L/usr/lib. I have already checked that.
dependency_libs=' -lpthread -lz -lm'

I link 3 libraries with libtool. The first one is linked with hdf lib that is in system (/usr/lib), the
second one is linked with vtk lib that is not in system ($VTKHOME) and the third one is linked 
with the 2 previous libs.

The problem is that there is another vtlk lib in system (/usr/lib) and libtool adds an -L/usr/lib when adding
hdf dependency so my third lib is linked with the two vtk libs (in system and in VTKHOME).

I have not found a way to handle this situation. What would be  the right way ?

Here is a simplified script of my link:

cd src/p1
/bin/sh ../../libtool --tag=CXX --mode=link g++ -o libhello.la -rpath /local/cchris/pkg/libtool/test22/myinstall/lib hello.lo -lhdf5

cd ../p2
/bin/sh ../../libtool --tag=CXX --mode=link g++ -o libprog.la -rpath /local/cchris/pkg/libtool/test22/myinstall/lib prog.lo -L/local/cchris/pkg/vtk/install/lib/vtk-5.6 -lvtkCommon

cd ../p3
/bin/sh ../../libtool --tag=CXX --mode=link g++ -o libviewer.la -rpath /local/cchris/pkg/libtool/test22/myinstall/lib viewer.lo ../p1/libhello.la ../p2/libprog.la
