Above all please do _not_ recommend building in-tree. Pretty please.

As mentioned before using --prefix=$WLD/foo + make install will make
things shorter/simpler

LD_LIBRARY_PATH="\
$WLD/foo/lib/\
${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}"

WESTON_BUILD_DIR="\
$WLD/build/weston/\
${WESTON_BUILD_DIR:+:$WESTON_BUILD_DIR}"

PKG_CONFIG_PATH="\
:$WLD/foo/lib/pkgconfig/
${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"

PATH="\
$WLD/foo/bin/\
:$PATH"

How about one honours the WLD that's already set since ...

... they will likely use it here ?

Use OOT builds, please.

The number of arguments is $#, why not use that one ?

With the above said, one can just check it and bail out if WLD invalid/unset ?

Then you can drop this (maybe) ?

And this ?
