I'm confused. Is there no way to link your library code on each platform? That way it will always run wherever it is ported to. It is not clear to me if this is what you are asking.
You seem to want to be able to link your code where ever it resides. You have two choices: link statically on the home machine, or compile to object code - ex: libfoo.a, on the home machine, then link a new PIC code library on each platform. Assuming your code links correctly against various installation of c++.
Static linking kind of defeats the purpose of a library. But it will work.
You cannot depend on version libstsdc++5 or 6 or whatever being available when you port your code. Lugging dynamic code from box to box is not always feasible. As you found out.

apr-config
APR-1-CONFIG(1) User Commands APR-1-CONFIG(1)
NAME
apr-1-config - Return metainformation about apr library
SYNOPSIS
apr-1-config [OPTION]
DESCRIPTION
The apr-1-config program is used to retrieve information about the apr library in the system. It is typically used to compile and link
against the library.
When linking with libtool, an application should do something like:
APR_LIBS="`apr-1-config --link-libtool --libs`"
or when linking directly:
APR_LIBS="`apr-1-config --link-ld --libs`"
An application should use the results of --cflags, --cppflags, --includes, and --ldflags in their build process.
OPTIONS
Known values for OPTION are:
--prefix[=DIR]
change prefix to DIR
--bindir
print location where binaries are installed
--includedir
print location where headers are installed
--cc print C compiler name
--cpp print C preprocessor name and any required options
--cflags
print C compiler flags
--cppflags
print C preprocessor flags
--includes
print include information
--ldflags
print linker flags
--libs print additional libraries to link against
--srcdir
print APR source directory
--installbuilddir print APR build helper directory
--link-ld
print link switch(es) for linking to APR
--link-libtool
print the libtool inputs for linking to APR
--shlib-path-var
print the name of the shared library path env var
--apr-la-file
print the path to the .la file, if available
--apr-so-ext
print the extensions of shared objects on this platform
--apr-lib-target
