[Discuss-gnuradio] cmake/MSVC build error (Windows XP)

[Don Ward]

While attempting to build GNU Radio (from git/master) on Windows XP with 
cmake and Visual C++ 2010 Express, I am getting:

4>------ Build started: Project: gengen_generated_index, Configuration: 
Release Win32 ------

MSB6006: "cmd.exe" exited with code 255.

This line appears in the file gengen_generated_index.vcxproj.  I suppose it 
was put there by cmake.  Any ideas on how to fix or work around this?  I can 
shorten the path names by building in another directory, but that seems like 
an unappealing and temporary workaround at best.

Thanks,
