You know how to add include paths to the preprocessor?
Use -I/some/path.  Add it to _CPPFLAGS, not _CXXFLAGS.

This looks wrong.  You should not have to add anything
compiler-internal.

Yes, precisely because your target is a library, not a program.
So use _LIBADD.

Do you have AC_PROG_CXX in configure.ac?
Did you recreate all the autotools-generated files consistently?
