eluna 库，实现Cpp和Lua互动的迷你库, 仅仅一个头文件包含

https://github.com/radiotail/eluna

1) 编译lua库

建一个Qt的pro文件, 自动创建则删除其他多余的只输入下列两句, 并添加已有文件, 将lua源码的*.c和*.h文件全部包含

TEMPLATE = lib

CONFIG += c++11

INCLUDEPATH += $$PWD
DESTDIR   = $$PWD/lib
HEADERS += \
    lapi.h \
    lauxlib.h \
    lcode.h \
    lctype.h \
    ldebug.h \
    ldo.h \
    lfunc.h \
    lgc.h \
    ljumptab.h \
    llex.h \
    llimits.h \
    lmem.h \
    lobject.h \
    lopcodes.h \
    lopnames.h \
    lparser.h \
    lprefix.h \
    lstate.h \
    lstring.h \
    ltable.h \
    ltests.h \
    ltm.h \
    lua.h \
    luaconf.h \
    lualib.h \
    lundump.h \
    lvm.h \
    lzio.h

SOURCES += \
    lapi.c \
    lauxlib.c \
    lbaselib.c \
    lcode.c \
    lcorolib.c \
    lctype.c \
    ldblib.c \
    ldebug.c \
    ldo.c \
    ldump.c \
    lfunc.c \
    lgc.c \
    linit.c \
    liolib.c \
    llex.c \
    lmathlib.c \
    lmem.c \
    loadlib.c \
    lobject.c \
    lopcodes.c \
    loslib.c \
    lparser.c \
    lstate.c \
    lstring.c \
    lstrlib.c \
    ltable.c \
    ltablib.c \
    ltests.c \
    ltm.c \
    lua.c \
    lundump.c \
    lutf8lib.c \
    lvm.c \
    lzio.c \
    onelua.c

(release编译)指令编译或者使用Creator编译, 编译后自然是无法运行的，若点击运行按钮则忽略无法运行提示，在工程文件所在目录下会有一个lib目录，查看liblua.a 和 lua.dll

2. 测试工程搭建

1) 在lua的源文件目录再创建一个lua.pri文件

INCLUDEPATH += $$PWD

CONFIG(release, debug|release): LIBS += -L$$PWD/lib -llua

HEADERS += \
    $$PWD/lapi.h \
    $$PWD/lauxlib.h \
    $$PWD/lcode.h \
    $$PWD/lctype.h \
    $$PWD/ldebug.h \
    $$PWD/ldo.h \
    $$PWD/lfunc.h \
    $$PWD/lgc.h \
    $$PWD/ljumptab.h \
    $$PWD/llex.h \
    $$PWD/llimits.h \
    $$PWD/lmem.h \
    $$PWD/lobject.h \
    $$PWD/lopcodes.h \
    $$PWD/lopnames.h \
    $$PWD/lparser.h \
    $$PWD/lprefix.h \
    $$PWD/lstate.h \
    $$PWD/lstring.h \
    $$PWD/ltable.h \
    $$PWD/ltests.h \
    $$PWD/ltm.h \
    $$PWD/lua.h \
    $$PWD/luaconf.h \
    $$PWD/lualib.h \
    $$PWD/lundump.h \
    $$PWD/lvm.h \
    $$PWD/lzio.h

2) 创建Qt工程, 将lua源码目录直接拷贝到新创建的Qt工程目录(带lua.pro和lua.pri的目录), 添加如下几句

DESTDIR   = $$PWD/bin
include($$PWD/lua/lua.pri)

3) 编写测试代码

#include <QCoreApplication>
