CMake is just always hell. Part of that hell is compiling CMake itself, which takes hours on some systems I've had to do it on. Autotools-based can be good or bad for cross-compiling. The biggest issue is that lots of people write broken tests that need to run test programs to get the results they want. The worst offender is gnulib, which has several such tests that are hard-coded to always-fail in the cross-compiling test, thus causing unwanted wrapper/replacement code to get pulled in and break functions that would otherwise work just fine on the target system. In concept, I think the Busybox "make menuconfig" style configuration is probably the worst of all. It's hard to automate and requires a learning curve for each program you want to build. The only reason it "works well" for cross-compiling with Busybox is that cross-compiling is a major usage case the maintainers care about. If you find a non-embedded-oriented program using this build system, you'll probably go through hell to get it to cross-compile right.
