A tool built to run on Microsoft's CRT, so not a Cygwin program.

> So, shouldn't you be complaining abount PowerShell as well?

I'm only using CMD as a launcher here (and made sure it does not modify
the input in unexpected ways). This is not about how a shell treats
commands, it's just about how a command line is interpreted by the
launched process. I validated this with Sysinternals Process Monitor.

CMake is not aware that it needs to generate Ninjafiles/Makefiles for
Cygwin programs and currently can't be made aware AFAIK. I had to resort
to a hack involving using undocumented CMAKE_<LANG>_COMPILER_ARG1
variables and a custom launcher tool that rewrites the command line. I
wish I did not have to venture into unsupported/undocumented territory
here.

Best regards
Oliver Old
