For those who are wondering: Doesn't build under osx, tho the issues initially don't see insurmountable, more that it hasn't been tried under CLANG.

[ 3%] Building CXX object contrib/libpoco/Foundation/CMakeFiles/PocoFoundation.dir/src/AbstractObserver.cpp.o error: unknown warning option '-Wno-unused-local-typedef' [-Werror,-Wunknown-warning-option] error: unknown warning option '-Wno-for-loop-analysis'; did you mean '-Wno-loop-analysis'? [-Werror,-Wunknown-warning-option] make[2]: * [contrib/libpoco/Foundation/CMakeFiles/PocoFoundation.dir/src/AbstractObserver.cpp.o] Error 1 make[1]: * [contrib/libpoco/Foundation/CMakeFiles/PocoFoundation.dir/all] Error 2

A bit of googling shows this is likely because Clang -Wall overrides any other flags set earlier which is apparently different than GCC. This makes me think they aren't lying when they say it supports linux in that they likely haven't tried building it on mac much.

That said it doesn't see to be using any crazy deps that don't support multiple platforms. Poco above is fully cross platform.

Note per apparent comments below: Lots of people develop or use macs and so they'd be interested if they'd have to have a VM or other option to use this. Since the readme is super thin and it just says Only linux xxx I felt they didn't have much info. I'm used to the days where people built projects that compiled everywhere but didn't build packages for them for some reason.
