Compilation fails if WITH_LUA ?= yes

[dazzag24]

Using Ubuntu 15.10.

Activated WITH_LUA ?= yes in config.mk.
Installed liblua5.2-dev as per the instructions at the end of the README.MD.

make then gives error:

$ make
cc -Wall -Werror -I/usr/include -DGHASHPREC=7 -DWITH_PING=1 -DWITH_LUA=1 pkg-config --cflags lua -DWITH_LMDB=1 -Imdb/ -DWITH_HTTP=1 -DJSON_INDENT=NULL -DSTORAGEDEFAULT="/var/spool/owntracks/recorder/store" -DDOCROOT="/var/spool/owntracks/recorder/htdocs" -c -o recorder.o recorder.c
Package lua was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua.pc'
to the PKG_CONFIG_PATH environment variable
No package 'lua' found
In file included from recorder.c:51:0:
hooks.h:5:18: fatal error: lua.h: No such file or directory
compilation terminated.
: recipe for target 'recorder.o' failed
make: *** [recorder.o] Error 1

Confirmed that pkg-config is also unable to find lua:

$ pkg-config --cflags lua
Package lua was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua.pc'
to the PKG_CONFIG_PATH environment variable
No package 'lua' found

However using "lua-5.2" works

$ pkg-config --cflags lua-5.2
-I/usr/include/lua5.2

I think config.mk needs editing to reflect the requirement that pkg-config is expecting the full lua+version string.

aeons ago... but i just found this while having trouble compiling with lua and for all coming after me, see the end of the config.mk file and adapt as follwing i.e.

LUA_CFLAGS = pkg-config --cflags lua-5.2
LUA_LIBS = pkg-config --libs lua-5.2
