This does not look like a bug to me.

The configure script is telling you that the lua library is present, 
but it can not find the matching lua.h file.
There are 2 possible reasons.

 
1) It could be because you have not  installed the  *-devel version of the library
to match the library itself

On my machine that is liblua5.2-5.2.3  and  lib64lua-devel-5.2.3 
but you may have a different version.  (The config output you show
mentions lua5.1).

2) Alternatively, you may correctly have the lua.h file installed but it is in 
a directory not on the default search path.
That is why the script output suggests
   configure: WARNING: please add path to lua.h to CPPFLAGS in Makefile

Of course as you say it is also possible to configure --without-lua
but then you will not be able to use the tikz terminal.
It would be better to install or identify the lua.h file.
