to build in a subdirectory. The additional directory is unfortunately
redundant when *not* building in a subdirectory, which is why I took
it out.
ext.sources = [ os.path.join(moddir, filename)
for filename in ext.sources ]
ext.include_dirs.append( '.' ) # to get config.h
+ ext.include_dirs.append( os.path.join(srcdir, './Include') )
# Try importing a module; if it's already been built statically,
# don't build it here
