If the enviroment variable SKIA_OUT is set the output of both
gyp and make will be redirected to that directory.

Makefile

# Makefile that wraps the Gyp and build steps for Unix and Mac (but not Windows)
# Uses "make" to build on Unix, and "xcodebuild" to build on Mac.
#
# Some usage examples (tested on both Linux and Mac):
#
# # Clean everything
# make clean
#
# # Build and run tests (in Debug mode)
# make tests
# out/Debug/tests
#
# # Build and run tests (in Release mode)
# make tests BUILDTYPE=Release
# out/Release/tests
#
# # Build bench and SampleApp (both in Release mode), and then run them
# make SampleApp bench BUILDTYPE=Release
# out/Release/bench -repeat 2
# out/Release/SampleApp
#
# # Build all targets (in Debug mode)
# make
#
# If you want more fine-grained control, you can run gyp and then build the
# gyp-generated projects yourself.
#
# See https://sites.google.com/site/skiadocs/ for complete documentation.
