scroggo 3965825b97 Check libpng directly into third_party/ 
With this change, the CMake build, which does not use DEPS to sync
external projects, is able to build and use the same version of libpng
that is used in other builds.

This will allow all platforms (including Google3 CMake build) to test on
the same version of libpng, so we do not need to make SkPngCodec support
all versions of libpng.

- Update CMakeLists.txt to use the checked in libpng.
- Check in libpng version 1.6.22rc01
- Update README.google
- Replace our old LICENSE file with the latest one from libpng

CMake build for Skia

This directory contains experiemental CMake build files for Skia. They are primarily targeted at building Skia as it would be shipped, not at day-to-day Skia development.

Quickstart

git clone https://skia.googlesource.com/skia.git
cd skia/cmake
cmake . -G Ninja     # Other CMake generators should work fine.
ninja
ls -l libskia.* example
./example
open example.png || xdg-open example.png

If that works, you should see "Hello World!" with a green-to-purple gradient.

Currently supported platforms

(None. This is still super experimental.)

Currently maybe-kinda-working platforms

  • x86-64 Mac OS X
  • x86-64 Ubuntu 15.04
  • x86-64 Windows 10, with extra caveats:
    • Compiles against DirectWrite, not GDI, for fonts
    • Configure with cmake . -G "Visual Studio 14 2015" .
    • Compile with cmake --build . --config Release .
    • Still has too many warnings.
    • Poorly tested as yet.
