I bet adding -lpcrecpp will do the trick if you're wanting to use the .a
file. My first post didn't really go into detail about how to do this
properly, so let me try to be more specific:
1. Open: $SVNDIR/src/osgPlugins/dae/CMakeLists.txt
2. Go down to line 27 and add "pcrecpp" to TARGET_EXTERNAL_LIB.
3. Re-run your master cmake command, so that it reconfigures.
4. Build!
If that doesn't work, then it's probably something more dubious. In
fact, I'd be willing to be it IS something dubious, because I've never
know Collada to mess this up. It definitely uses libpcrecpp, but it's
own build system should have linked that in when building the archive.
