I've built git under aboriginal before...

(And the git guys later said that ./configure is just a wrapper for  
windows builds, and I should just supply the make variables for all my  
options. Either way, worked for me.)

Haven't tried cmake. I vaguely recall that's python? I've bulit python  
before, back when I was trying to build gentoo...

Looks like it's just ./configure; make; make install and it's done  
after zlib and ncurses (the mnt/package-list file controls the order of  
builds and the mnt/build directory contains each package's build  
script...)

Neither are hugely current, but they worked at one point...

Which is why I had to bypass the ./configure and specify that variable  
by hand on the make command line.

I very, very vaguely remember a mention of a cmake bug with libuClibc++.

I've been meaning to try llvm's libc++ at some point. Needing it as a  
chicken and egg problem sounds unhappy, though...

The problem with libstdc++ is that it's part of the gcc source. It's  
not a standalone package. And it does NOT like to cross-compile, nor is  
it really happy building against anything except glibc. (I've fought  
against it before. Not recently, but it was annoying at the time...)

What do you need cmake for? (The llvm build?)
