1# Makefile that wraps the Gyp and build steps for Unix and Mac (but not Windows)
2# Uses "ninja" to build the code.
3#
4# Some usage examples (tested on both Linux and Mac):
5#
6#   # Clean everything
7#   make clean
8#
9#   # Build and run tests (in Debug mode)
10#   make dm
11#   out/Debug/dm
12#
13#   # Build and run tests (in Release mode)
14#   make dm BUILDTYPE=Release
15#   out/Release/dm
16#
17#   # Build bench and SampleApp (both in Release mode), and then run them
18#   make SampleApp bench BUILDTYPE=Release
19#   out/Release/bench -repeat 2
20#   out/Release/SampleApp
21#
22#   # Build all targets (in Debug mode)
23#   make
24#
25# If you want more fine-grained control, you can run gyp and then build the
26# gyp-generated projects yourself.
