Looking at the docs a bit closer, it seems like this is the better solution: set( CMAKE_C_FLAGS_INIT -m32 ) set( CMAKE_CXX_FLAGS_INIT -m32 ) Not sure if you'd agree, but at least I can verify it is working. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

I still don't remember why I started using it, it was definitely to work around some sort of issue. What is the proper, public API solution that gives identical functionality? Should I be using `CMAKE_C_COMPILER` instead, and appending to it as a string from my toolchain file?

[cmake-developers] CMAKE_C_COMPILER_ARG# not documented?
I can't remember where I heard about these CMake variables, but in one of my toolchain files I do this: set( CMAKE_C_COMPILER_ARG1 -m32 ) set( CMAKE_CXX_COMPILER_ARG1 -m32 ) On the [cmake variables][1] page, these are not documented. I expected an entry somewhere like `CMAKE__COMPILER_ARG<#>` but there isn't one. Are these documented? If so, where? If not, I'll create an issue on the gitlab project page to make sure that gets done at some point. I would offer to do it but I'm not too sure what the variables do myself, nor am I sure what the upper limit for ARG is.
