<p class="MsoNormal">I personally use cmake with multiple cross toolchains successfully. I guess it depends on what you are trying to achieve. I prefer it because I can use the same CMakeLists.txt to build natively on linux/mac/windows, as well as cross-compile
against an embedded arm linux. I'd also agree with the previous discussion about using a toolchain file for your platform, it does simplify things.<o:p></o:p></p>
