# 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 two diadvantages:
# 1.) Out-of-tree builds are not straight forward and require
#     manually cloning the submodules into the build system.
#     `make distcheck` is consequently also broken.
# 2.) 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.
