How to build with lua54?

[Pi-Cla]

Previously on SILE 0.14.17 I could build with lua54 and the interpreter would be detected properly:

[   23s] checking for a Lua interpreter with version >= 5.1... Hello Lua 5.4!
[   23s] lua
[   23s] checking for lua... /usr/bin/lua
[   23s] checking for lua version... 5.4
[   23s] checking for lua platform... unknown
[   23s] checking for lua script directory... ${prefix}/share/lua/5.4
[   23s] checking for lua module directory... ${exec_prefix}/lib/lua/5.4
[   23s] checking if LUA_VERSION is defined... yes
[   23s] checking for lua.h... no
[   24s] checking for lualib.h... no
[   24s] checking for lauxlib.h... no
[   24s] checking for luaconf.h... no
[   24s] checking for Lua headers in... /usr/include/lua5.4
[   24s] checking for lua.h... yes
[   24s] checking for lualib.h... yes
[   24s] checking for lauxlib.h... yes
[   24s] checking for luaconf.h... yes
[   24s] checking for Lua header version... 5.4
[   24s] checking if Lua header version matches 5.4... yes

but now I get this instead:

[    5s] checking for a Lua interpreter with version >= 5.1... none
[    5s] configure: error: cannot find suitable Lua interpreter

Try ./configure --without-luajit. The default is now to try to use LuaJIT and evidently that's what is not being found on your system. Also note that by default SILE tries to match versions with the Lua on your system (hence looking for it at build time) but it does not actually use your system's Lua at run time, it includes it's own interpreter and runs on that. If you want to skip even attempting to match your system's Lua you should be able to use --without-system-lua-sources in which case it will download and use vendored sources when building it's internal VM.

Note that LuaJIT makes SILE run over twice as fast on long documents and we highly recomend using it, but everything is still 100% PUC Lua compatible so you are free to use that too.

Thanks now it accepts lua54 again
