Hi all,
You should add pkg-config to the list of dependencies in the README. It is
required if you want to build with Lua support. Also, it might be a good
idea to check for pkg-config presence in the Makefile. For example, if you
try
> make LUA_IMPLEMENTATION=JIT
with LuaJIT installed and pkg-config not installed, the error message will
be
LuaJIT specified via LUA_IMPLEMENTATION=JIT, but library could not be
found.
which is misleading.
Thanks,

Thanks for the report; this is a good idea.
Do you have any ideas on a fallback, for when pkg-config isn't
available? I know for LUA_IMPLEMENTATION=VANILLA, we can probably just
add a -llua to LIBS, but it's not as straight forward for
LUA_IMPLEMENTATION=JIT. Any feedback would be most appreciated.

Jason,
I'm no Makefile expert, but a solution ? la CMake involves checking for the
library/header existence in common library/header location (/usr/...,
/usr/local/..., etc). If the library is found, we use it, otherwise, we
prompt a relevant error message. CMake has its own Find* mechanism; isn't
the autotools ./configure exactly for that purpose?
HTH,
