1) Check that the boost libraries are in the same place that they are on my system (should be as you're on 64-bit), type:
locate libboost_thread.so
This should come up with /usr/lib/x86_64-linux-gnu/libboost_thread.so (and possibly other results). Check libboost_system.so libpthread.so similarly, I suspect they'll all be in the same place as mine.
2) (more likely to work) Delete CMakeCache.txt in your project build directory and regenerate (i.e. cmake [whatever]). The old entry (CGAL_3RD_PARTY_LIBRARIES) is likely to be saved in your cache from before you made the changes I suggested.
No worries. So try two things:
1) Check that the boost libraries are in the same place that they are on my system (should be as you're on 64-bit), type:
locate libboost_thread.so
This should come up with /usr/lib/ x86_64- linux-gnu/ libboost_ thread. so (and possibly other results). Check libboost_system.so libpthread.so similarly, I suspect they'll all be in the same place as mine.
2) (more likely to work) Delete CMakeCache.txt in your project build directory and regenerate (i.e. cmake [whatever]). The old entry (CGAL_3RD_ PARTY_LIBRARIES ) is likely to be saved in your cache from before you made the changes I suggested.
