问题
I am trying to configure cmake to build for 32bit and 64bit separately...
So far 64bit is easy as I just need to add -A x64
cmake -G "Visual Studio 16 2019" -A x64
But I am not able to set 32bit arch.
Official documentation suggest -A Win32 or -T host=x86
https://cmake.org/cmake/help/latest/generator/Visual%20Studio%2016%202019.html
Even with them I am not able to set x86 host
What I have tried:
cmake -G "Visual Studio 16 2019" -DCMAKE_GENERATOR_PLATFORM=x86
cmake -G "Visual Studio 16 2019" -A Win32
cmake -G "Visual Studio 16 2019" -A Win32 -T host=x86
cmake -G "Visual Studio 16 2019" -A Win32 host=x86
Nothing is working, Here is log I am getting all the time...

回答1:
It was related to node-js...
I just wrote generator with Win32 and passed arch in node-js part of package.json
npm config set cmake_js_arch ia32 && cmake-js compile cmake -G \"Visual Studio 16 2019\" -A Win32
I am using cmake to build c++ code DLL for a node project, So it is necessary to run it from command line.
cmake-js is a node package for Cmake and that command is telling cmake-js to set arch ia32
