Build with prebuilt Lua Version

[aryajur]

I am trying to build with a pre-build Lua version. meson was not able to find my Lua version. I then defined a lua.pc file:

`
prefix=/path/to/my/lua
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/inc

Name: lua
Description: Lua programming language
Version: 5.3
Libs: -L${libdir} -llua
Cflags: -I${includedir}
`

I then get the following error:

Found pkg-config: C:\msys64\mingw32\bin/pkg-config.EXE (1.8.0)
Found CMake: C:\msys64\mingw32\bin/cmake.EXE (3.25.1)

../meson.build:144:8: ERROR: C++ shared or static library 'lua53' not found

the libdir already has lua53.dll file in there. After I renamed lua53.dll to lua.dll then that worked. But now it was not able to find the executable Lua.

So I made the deps subdirectory and put the lua53 executable and dll in there with all the include files in the deps/include subdirectory. Then I ran the command:

meson .. -Dlua_version=5.3 -Dlua_path=/path/to/cffi-lua-0.2.3/build/deps/lua.exe

that worked!

Now when I run ninja I get all fatal errors that it cannot find lua.hpp.

So I had to manually edit build.ninja to add the "-Ideps/include" term in the commands.
After that it worked.
