[Xcb] xcb-proto DBE extension

 Hi again,

 I am trying to build in a local directory, I don't want to mess up my X
installation since I am running Optimus PRIME ... and it's not super mature
... so I figured I would build and do a staticly linked binary for testing,
however even when setting PKG_CONFIG_PATH the make of libxcb fails with :

Making all in src
make[1]: Går till katalogen ”/home/ls/src/xdbe/mainline/libxcb/src”
make[1]: *** Ingen regel för att skapa målet ”/usr/local/share/xcb/”, som
behövs av ”xproto.c”.  Stannar.
make[1]: Lämnar katalogen ”/home/ls/src/xdbe/mainline/libxcb/src”
Makefile:791: receptet för målet ”all-recursive” misslyckades
make: *** [all-recursive] Fel 1

This does not happen when I build for libxcb-1.11.1 ... which is the
version the system is running, so I figure the build picks up the system
files in this case but not when doing a local build.

I know the autotools a bit, but I am not good with package-config .... so
any help appreciated.

My educated guess is that I need to do a 'dummy' install somewhere ,
specified with --prefix to configure, does this sound about right ?

Btw. the whole generation of protocoll bindings is SWEET ... very nice ...
a pleasant surprise.

 / regards, Lars Segerlund.
