[GoogleCodeExporter]

System:

1. Window7 64 Bit
2. VS 2013 Update 4

What steps will reproduce the problem?
According to 
https://code.google.com/p/libyuv/wiki/GettingStarted

1. Download and install depot_tools following steps in 
https://sites.google.com/a/chromium.org/dev/developers/how-tos/install-depot-too
ls
2. Start cmd prompt with admin rights. Create folder libyuv (e.g. 
c:\vs\libs\libyuv)
3. Run gclient config http://libyuv.googlecode.com/svn/trunk
4. Run gclient sync
5. set GYP_DEFINES=target_arch=ia32
6. Run "call python gyp_libyuv -fninja -G msvs_version=2013 --depth=. 
libyuv_test.gyp" or "call python gyp_libyuv -fninja -G msvs_version=2013 
--depth=. libyuv.gyp"

Output -> 

C:\VS\Libs\libyuv\trunk>call python gyp_libyuv -fninja -G msvs_version=2013 
--depth=.
libyuv_test.gyp
Traceback (most recent call last):
  File "gyp_libyuv", line 23, in <module>
    import gyp_chromium
ImportError: No module named gyp_chromium


The python script gyp_libyuv tries to find the module gyp_chromium
in folder "<checkout_root>\build" ->
sys.path.insert(0, os.path.join(checkout_root, 'build'))

But this module is lokated in folder
"<checkout_root>\chromium\src\build"

7.
After inserting this line in to script:
sys.path.insert(0, os.path.join(checkout_root, 'chromium', 'src', 'build'))

the gyp_chromium module was found but another error popped out:

C:\VS\Libs\libyuv\trunk>call python gyp_libyuv -fninja -G msvs_version=2013 --de
pth=. libyuv_test.gyp
