If the enviroment variable SKIA_OUT is set the output of both gyp and make will be redirected to that directory. Review URL: https://codereview.appspot.com/6782095 git-svn-id: http://skia.googlecode.com/svn/trunk@6578 2bbb7eff-a529-9590-31e7-b0007b416f81

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.
