Re: [Xen-devel] [PATCH VTPM v4 3/5] vtpm/vtpmmgr and required libs to stubdom/Makefile

[Matthew Fioravante <matthew.fioravante@xxxxxxxxxx>]

As annoying as it may be, I think having a configure script or something 
similar is the only right answer. More hidden makefile variables and 
hacks makes everything more complicated. Before the existence of the 
configure script Xen's build system was a huge pain to work with. Its 
still not perfect.
So here are 2 proposals:

Add a configure.ac to stubdom. I can whip up a simple one where you can 
enable/disable specific stub domains. Other options could be setting the 
fetch urls for the libraries. People can add more options later. Now if 
people disable vtpm, the check for cmake goes away.
Move /tools/configure.ac to /configure.ac. Use this configure script to 
configure the entire build. /Makefile still exists and works with or 
without configuring, to enable building of the hypervisor.
If we don't want to do this now, then I vote to just make cmake a 
dependency for Xen without adding messy conditional hacks.
