Remove cmake/
We've stopped testing and updating the experimental CMakeLists.txt file. A guide to building Skia with GN is available at skia.org/user/build.

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
|
||||
----------
|
||||
|
||||
<!--?prettify lang=sh?-->
|
||||
|
||||
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.
