With GNU Make this worked pretty fine with WML 1.7.4, when I
created two different Target environments out of common sources
(actually the only difference was a "comments" button for the
intranet-version which should not appear in the internet 
version, but I think one could realize entirely different
layouts or different languages in different target paths
through this).

The only problem I had was that BASENAME and DIRNAME were
determined in a way that didn't match my expectation.

user@host:~/targets $ wml ../sources/index.wml

would have set


instead of


As a quick and dirty workaround I included the following lines
in my templates:

# Tweak for WML 1.7.4 being called from a directory
# other than the one where the source is.
# WML_SRC_BASENAME only does s/.wml$// but not s|(.*)/||
# WML_SRC_DIRNAME is set to `pwd` instead of $1 of prev. regex

<set-var WML_SRC_BASENAME=<substring
    <get-var WML_SRC_FILENAME>
    <match <get-var WML_SRC_FILENAME> "[^/]*$" action=startpos>
    <match <get-var WML_SRC_FILENAME> "\.wm.$" action=startpos>
<set-var WML_SRC_DIRNAME=<substring
    <get-var WML_SRC_FILENAME>
    <match <get-var WML_SRC_FILENAME> "[^/]*$" action=startpos>

which delivers at least


where WML_SRC_DIRNAME could now be prepended to the
WML_SRC_BUGGY_DIRNAME and put through &canonpath() of
wml::sup::path to get the expected result.

But since this is really dirty and I don't know whether it
still works under WML 2.0 (which to be testing I'm still looking
forward to) I think If you really consider this senseful you
should implement it directly into wml.
