https://github.com/zeromq/libzmq/blob/36d6b5d923e997d6d49b34c6c1e822800ef08b67/CMakeLists.txt#L895



Whole Program Optimization and Link Time Code Generation is known to cause issues on Windows (msbuild) with even minor changes in releases of the msbuild/Visual Studio toolchain.



I currently have an issue where libzmq is built by a different minor version of the toolchain from my application. My application does not use /GL or /LTCG and still fails to build because it statically links libzmq.



Link time code generation just ends up being more problematic versus anything gained in performance from whole program optimization. I don't think any of the other zeromq libs are using /GL and /LTCG.
