Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] Daisy build info

OK, I now have the Daisy toolchain installed, and the latest Csound
develop. Following the instruction, I navigate to the build dir and execute

cmake .. -DCMAKE_INSTALL_PREFIX=../Daisy
> -DCUSTOM_CMAKE=../Daisy/Custom.cmake
> -DCMAKE_TOOLCHAIN_FILE=../Daisy/crosscompile.cmake


this produces an error:

-- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual
Studio/2019/Community/VC/Tools/MSVC/14.29.30133/bin/Hostx64/x64/cl.exe -

  is not able to compile a simple test program.

  It fails with the following output:

So apparently it is passing gcc options to the MSVC compiler. What do I
need to do to get it to use the Daisy toolchain instead?
