chrominu工具链必须要会啊

之前一直很抗拒使用gyp等待chrominu，喜欢cmake。但是不使用chromium工具链去编译，分析chromium确实非常痛苦啊，，，
好在这几天网络环境好，成功按照http://www.chromium.org/developers/how-tos/build-instructions-windows#TOC-Building-Chromium创建了编译环境。
不多大部分细节都不知道，没办法的事情。最终还是要自己理解整个工程才OK啊

gyp工具用法

例子：tools\gyp\gyp.bat --depth . -D component=shared_library --no-circular-check -G msvs_version=2008 -Ibuild/common.gypi build_add/all.gyp

添加参数用-D

Building in Visual Studio

You can use:

    set GYP_GENERATORS=msvs-ninja,ninja

and then

        gclient runhooks

gclient sync --force

Usage: gyp-script.py [options ...] [build_file ...]

Options:

  -h, --help            show this help message and exit

  --build=CONFIGS       configuration for build after project generation

  --check               check format of gyp files

  --config-dir=CONFIG_DIR

                        The location for configuration files like

                        include.gypi.

  -d DEBUGMODE, --debug=DEBUGMODE

                        turn on a debugging mode for debugging GYP.  Supported

                        modes are "variables", "includes" and "general" or

                        "all" for all of them.

  -D VAR=VAL            sets variable VAR to value VAL

  --depth=PATH          set DEPTH gyp variable to a relative path to PATH

  -f FORMATS, --format=FORMATS

                        output formats to generate

  -G FLAG=VAL           sets generator flag FLAG to VAL

  --generator-output=DIR

                        puts generated build files under DIR

  --ignore-environment  do not read options from environment variables

  -I INCLUDE, --include=INCLUDE

                        files to include in all loaded .gyp files

  --msvs-version=MSVS_VERSION

                        Deprecated; use -G msvs_version=MSVS_VERSION instead

  --no-circular-check   don't check for circular relationships between files

  --parallel            Use multiprocessing for speed (experimental)

  -S SUFFIX, --suffix=SUFFIX

                        suffix to add to generated files

  --toplevel-dir=DIR    directory to use as the root of the source tree
