[tlbuild] [CWEB] Why should I care about harfbuzz?

[Andreas Scherer]

Dear all,

in preparation of TL 2019, I used the attached shell skript to
test-compile CWEB -- and not much more.

Recently, the invocation './tl-disable 2>&1 | tee cweb.build' started to
fail with this error message:

In file included from
../../../texk/web2c/luatexdir/luaharfbuzz/src/luaharfbuzz/blob.c:1:0:
../../../texk/web2c/luatexdir/luaharfbuzz/src/luaharfbuzz/luaharfbuzz.h:4:10:
fatal error: hb.h: No such file or directory
 #include <hb.h>
          ^~~~~~
compilation terminated.

Obviously, I should try to add some more '--disable-OPTIONS' to suppress
compilation of icu, harfbuzz, luaharfbuzz, w.h.y.

Could someone with more indepth knowledge advise me how to compile CWEB
from the TL sources again? TIA.

Greetings, Andreas
