Nicola Pero d6d6f0a035 Use shared headers.make code to manage headers; do not set FINAL_LIBRARY_INSTALL_DIR 
if already set, so that clibrary.make can include us

# Allow the user GNUmakefile to define xxx_SOVERSION to replace the
# default SOVERSION for this library.
# Effect of the value of SOVERSION -
# suppose your library is libgnustep-base.1.0.0 - if you do nothing,
# SOVERSION=1, and we prepare the symlink libgnustep-base.so.1 -->
# libgnustep-base.so.1.0.0 and tell the linker that it should
# remember that any application compiled against this library need to
# use version .1 of the library. So at runtime, the dynamical linker
# will search for libgnustep-base.so.1. This is important if you
# install multiple versions of the same library. The default is that
# if you install a new version of a library with the same major
# number, the new version replaces the old one, and all applications
# which were using the old one now use the new one. If you install a
# library with a different major number, the old apps will still use
# the old library, while newly compiled apps will use the new one.
# If you redefine SOVERSION to be for example 1.0, then we prepare
# the symlink libgnustep-base.so.1.0 --> libgnustep-base.so.1.0.0
# instead, and tell the linker to remember 1.0. So at runtime, the
# dynamical linker will search for libgnustep-base.so.1.0. The
# effect of changing SOVERSION to major.minor as in this example is
# that if you install a new version with the same major.minor
# version, that replaces the old one also for old applications, but
# if you install a new library with the same major version but a
# *different* minor version, that is used in new apps, but old apps
# still use the old version.
