The install prefix is set at the "configure" step - CMake is quite
similar to Autoconf in this respect. To put an example, configuring
SimGear on a setup with TerraSync/SVN explicitly disabled would look
like this:
# ${SRC}/simgear > cmake -D CMAKE_INSTALL_PREFIX=${FG_HOME} -D
ENABLE_LIBSVN=OFF .
# ${SRC}/simgear > make
# ${SRC}/simgear > make install
Additional flags are optional, similarly to Automake.

CMake in FlightGear does exactly this. "configure" .... eeeh, "cmake"
with "-D CMAKE_INSTALL_PREFIX=${FG_HOME}" and it'll find SimGear in
exactly this place. At least it's working this way for me and we'll
try to make sure it will work on other people's setups the same way -
if it doesn't already do so. Custom flags to find custom
pre-requisites in custom places are being applied in a familiar manner
(like "-D RTI_LIBRARY=/opt/OpenRTI/lib/libRTI-NG.so" for example).
There are six weeks left until we're caught by the Automake deadline,
two more months until feature freeze plus another two months until
release. I'm pretty certain that's sufficient time to get the pending
issues ironed out until release - at least for those setups whose
maintainers are seriously interested in having a working build.
Well, you'll never catch 100 % of the "help me, my build is broken -
but I won't tell you, how ...."'s - that's life ;-)
Cheers,
Martin.
