Unable to build (libcpp.lib not found)

Hello,

For now it's impossible to build node correctly. This is what I get:

FAILED: node.dll node.dll.lib node.dll.pdb

ninja: build stopped: subcommand failed.

I also tried to call build manually like this:

f:\nwjs\src>autoninja -C out\nw libcpp
"f:\dev\depot_tools\bootstrap-2@3_8_10_chromium_26_bin\python3\bin\python3.exe" F:\dev\depot_tools\ninja.py -C out\nw libcpp -j 34
ninja: Entering directory `out\nw'
[2/2] LIB obj/buildtools/third_party/libc++/libcpp.lib

f:\nwjs\src>autoninja -C out\nw libc++
"f:\dev\depot_tools\bootstrap-2@3_8_10_chromium_26_bin\python3\bin\python3.exe" F:\dev\depot_tools\ninja.py -C out\nw libc++ -j 34
ninja: Entering directory `out\nw'
ninja: no work to do.

And it shows, that it does something, but doesn't generate any output file in case of libcpp.

Start with the reported autoninja commands for libcpp and libc++ and the out\nw build paths, then inspect why libcpp.lib is not available to the node.dll link step. Reproduce the link and resolve the missing library and RuntimeLibrary mismatch; done means the build produces node.dll successfully.
