# Default build options
###################################################################################################
#  NPROCS:                Number of processors to use for parallel jobs
#  GENERATOR:             CMake generator to configure and build with
#  PREFIX:                Where to install luvi, defaults to /usr/local or C:\Program Files\luvit
#  BINPREFIX:             Where to install luvi binary, defaults to $PREFIX/bin
#  EXTRA_CONFIGURE_FLAGS: Extra options to pass to cmake when configuring
#  EXTRA_BUILD_FLAGS:     Extra options to pass to make when building
#
#  CMAKE_BUILD_TYPE:   The cmake build type to use, defaults to Release
#  WITH_AMALG:         Whether to build the lua amalgamated, will use more memory but is faster
#  WITH_LUA_ENGINE:    Which lua engine to use, defaults to LuaJIT
#  WITH_SHARED_LIBLUV: Whether to use libluv as a shared library.
#    			       Note: Shared libluv implies shared libuv and luajit.
#
#  WITH_{OPENSSL,PCRE,LPEG,ZLIB}: Whether to include the given library in the build
#  WITH_SHARED_{OPENSSL,PCRE,LPEG,ZLIB}: Whether to use shared or static versions of the given library

### Build targets

default: luvi

# This does the actual build and configures as default flavor is there is no build folder.

### Directories and dependencies

# Ensure the build prefix exists, ie. we have configured the build
$(BUILD_PREFIX):
	@echo "Please run 'make tiny' or 'make regular' first to configure"

# In case the user forgot to pull in submodules, grab them.

### Configuration targets

# Configure the build with minimal dependencies
tiny: deps/luv/CMakeLists.txt

# Configure the build with any libraries requested
regular: deps/luv/CMakeLists.txt
