build on windows does not find ninja

[felix.g...@tracxpoint.com]

Hi

I am trying to install caffe on windows by following the instructions on GitHub.

I got to the stage where I need to run

scripts\build_win.cmd

I installed Ninja through conda but the build script cannot find it. I get the following error message:

The system cannot find the drive specified.

What am I doing wrong? 

I thought the build script would contain a field where I can supply the paath to Ninja but apparently it doesn't. Is theer some other place I need to configure?

Thanks!

If I am right, you probably don want to use Ninja with MSVC. Try to change the script to disable ninja, and use cmake instead.
