[Libreoffice] o3tl/cow_wrapper.hxx not found

Here the build mechanism sets some shell variables that will then be
used later on the same command line. (Yeah, weird, but apparently this
*is* a good idea, I don't know or recall the details.)

[...], looks fine so far

But these are all screwed up, the $O and $S shell variables are not
expanded, and even if they were, they are used in locations that don't
make sense.

You are supposed to see -I flags with the $O and $S expanded. In your
case O=c:/cygwin/home/Simon/git/libo/solver/wntmsci12.pro and
S=c:/cygwin/home/Simon/git/libo as far as I can see).

For instance the first -I option there, -IC:/cygwin$O/inc/stl , would
with $O expanded be
-IC:/cygwinc:/cygwin/home/Simon/git/libo/solver/wntmsci12.pro/inc/stl
which of course makes no sense.

There must be something wrong in the gbuild make function mechanisms
that mishandles your case. I wonder if it is the fact that you are
building in your home directory, does the fact that the build location
starts with c:/cygwin confuse some substitution pattern, or something?
I will try to investigate.

(To compare, I see the following corresponding output:

R=c:/ooo/git/master &&
O=$R/core/solver/wntmsci12 &&
W=$R/core/workdir/wntmsci12 &&
S=$R/core &&
[...]
-IC:/ooo/git/master/core/solver/wntmsci12/inc/stl
-IC:/ooo/git/master/core/solver/wntmsci12/inc/external
-IC:/ooo/git/master/core/solver/wntmsci12/inc
-IC:/ooo/git/master/core/solenv/wntmsci12/inc
-IC:/ooo/git/master/core/solenv/inc
-IC:/ooo/git/master/core/res
