# We use the existing Scintilla/Lexilla Makefile build system to
# avoid redundancies and maintainance overhead.
# These build systems produce static libraries (*.a).
# This however has the following disadvantages:
#
# * We cannot add plain static libraries to libtool convenience
#   libraries using LIBADD.
#   Therefore, we cannot wrap Scintilla and Lexilla into a convenience
#   library.
#   That's why this file must instead be included everywhere where
#   scintilla.a and liblexilla.a are referenced and they must be added
#   to programs using LDADD.
