Hi James,
This problem was happening in BOTH Ubuntu linux,
and in XP WIN32...
BUT at least in Ubuntu, I think some of the problem
was that I was NOT deleting the CMakeCache.txt file
each time I modified the script for another try...
Remember the abort I was getting was :-
Could NOT find SimGear (missing: SIMGEAR_VERSION_OK)
Now I seem to have found a combination that works -
(a) Setting the environment -
makefg: Done export SIMGEAR_DIR=/media/Disk2/FG/fg17/install/simgear
AND
(b) adding SIMGEAR_INCLUDE_DIR
makefg: Will do 'cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_CXX_FLAGS=-O3 -D LIB_POSTFIX= \
-D CMAKE_INSTALL_PREFIX:PATH=/media/Disk2/FG/fg17/install/fgfs \
-D ENABLE_RTI=OFF -D CMAKE_VERBOSE_MAKEFILE=TRUE \
-D SIMGEAR_LIBRARIES=/media/Disk2/FG/fg17/install/simgear/lib \
-D SIMGEAR_INCLUDE_DIR=/media/Disk2/FG/fg17/install/simgear/include\
.'
Maybe, as you have suggested, this is over kill,
setting BOTH SIMGEAR_DIR in the environment,
AND passing SIMGEAR_INCLUDE_DIR to cmake,
and when I feel comfortable, I will eliminate
one or the other for further testing...
BUT now I have reached another wall...
fgjs will not link ;=((

This is missing SG gzip and logbuf, and can NOT see
ANY SG libraries in the link, like -lsgdebug,
etc...very puzzling???
Maybe this is related to EVENT_INPUT which
defaults ON for APPLE, but has a comment
for linux -
elseif(CMAKE_SYSTEM_NAME MATCHES "Linux")
# disabled while DBus / HAL / udev issues are decided
#set(EVENT_INPUT_DEFAULT 1)
and later
option(EVENT_INPUT
"Set to ON to build FlightGear with event-based Input support"
${EVENT_INPUT_DEFAULT})
but maybe this has nothing to do with it...
Anyway, out of time for exploration tonight,
but look forward to any suggestions for
continuing tomorrow...
As mentioned I am trying to update my script to
use CMake... The previous versions of the script are
published here -
http://geoffair.org/fg/fgfs-052.htm
BUT because this 'cmake' version 1.3.5 is
not yet fully tested, and sometimes failing,
I have not yet published it on that page, but a
copy of it is here for testing :-
http://geoffair.org/tmp/makefg

Geoff.
