[ft-devel] `make refdoc' fails if builddir != srcdir

[Werner LEMBERG]

The title says it all.

  $ mkdir freetype2.compiled
  $ cd freetype2.compiled
  $ .../path/to/freetype2/configure

  $ make refdoc
  Running docwriter...
  python3 -m docwriter \
          --prefix=ft2 \
          --title=FreeType-2.9.1 \
          --output=.../freetype2.compiled/reference \
          .../freetype2/include/freetype/*.h \
          .../freetype2/include/freetype/config/*.h \
          .../freetype2/include/freetype/cache/*.h
  INFO    -  Cleaning output directory
  INFO    -  Building markdown documentation to directory:
             ../freetype2.compiled/reference/markdown
  Traceback (most recent call last):
    ...
    new_file   = open( filename, "w" )
  FileNotFoundError: [Errno 2]
  No such file or directory:
    '.../freetype2.compiled/reference/markdown/index.md'

Reason of the failure is that there isn't a `markdown' subdirectory.
To have a functional `reference' directory tree I thus suggest that
the files and directories from srcdir's `reference' tree get copied to
builddir.
