Hopefully this tells the Expat headers not to do any clever
declspec(import) or export stuff, which we don't want since we only
use the symbols within SimGearCore, and don't export them.
Switch back to including the bundled expat sources directly in the
targets, since transitive linking of static libs is very awkward.
Makes static build happy again (let's see what else breaks)
Renamed bundled Expat headers to avoid any
possibility of accidental including system headers when
using bundled Expat, or vice-versa. Should help with SVN
crashes reported by Thomas.
Check for the 3rdparty dir in the parent of build dir, not the parent of the source dir. For the recommended build layout, this is the same location, but for super-builds using fgmeta it's not (and the source tree should not be touched).
If this causes anyone issues, please let me know, since it's possible more flexibility is needed to set the path explicitly.
Basic library infrastructure, catalog download/refresh, and package install,
uninstall and update. Disabled at cmake time by default, and not yet hooked
into FlightGear.
ENABLE_SOUND=0 now works when configuring SimGear, and libSimGearScene can be linked without OpenAL. However, more testing of FlightGear in this mode is needed before it's officially supported!
Ubuntu/Debian introduced "multiarch" library directories, which is
unsupported by CMake <= 2.8.10. Add manual search paths as a workaround.
Currently it is only needed for libsvn, but it is needed for any lib
which is converted to the new directory standard.
At least one Linux distribution packager of FG has complained that we're bundling expat in our binaries. To keep them happy, add the option (-DSYSTEM_EXPAT=1 at cmake time) to use the system expat instead.
For the moment (and simplicity), this requires building SIMGEAR_SHARED (which is fired to on by selecting the option).
Adapt the freealut code into a WAV-file reader. As a side-effect, it would now be possible to deploy WAV files compressed with gzip, since we use ZLib's gzread functions to read from disk.
Status message are almost invisible - use warning message instead, so
builders/packagers actually notice a missing dependency.
Also add some useful hints.
This removes the other still present dependency on osg
in the future sgcore library.
It also remove the need for the NO_OPENSCENEGRAPH_INTERFACE
compile time definition.
