You might also try CMake[1] as alternative to autotools. 
This works for most OSes, compilers and architectures.

// Find Lua and set up LUA_ variables
FIND_PACKAGE(Lua51 REQUIRED)
INCLUDE_DIRECTORIES(${LUA_INCLUDE_DIR})

// Build module
ADD_LIBRARY(myModule MODULE mySource.c myOtherSource.c)
TARGET_LINK_LIBRARIES(myModule ${LUA_LIBRARY})

// Remove any prefix from the module such as "lib" or "cyg" depending on platform
SET_TARGET_PROPERTIES(myModule PROPERTIES PREFIX "")
