	[ 'node_use_sqlite=="true"', {
	'sources': [
	'<@(node_sqlite_sources)',
	],
	}],
	[ 'node_use_ffi=="true"', {
	'sources': [
	'<@(node_ffi_sources)',
	],
	'conditions': [
	[ 'node_shared_ffi=="false"', {
	'dependencies': [
	'deps/libffi/libffi.gyp:libffi',
	],
	}],

	[ 'node_use_sqlite=="true"', {
	'sources': [
	'<@(node_sqlite_sources)',

	[ 'node_use_ffi=="true"', {
	'sources': [
	'<@(node_ffi_sources)',

	[ 'node_shared_ffi=="false"', {
	'dependencies': [
