Yes, I just said that I observed a failure that seemed unrelated to
libtiff.

What I'm seeing looks like something in pthreads changed:
Linking CXX executable ../../bin/osgversion
cd /builddir/build/BUILD/OpenSceneGraph-3.0.1/BUILD/applications/osgversion &&
/usr/bin/cmake -E cmake_link_script

/usr/bin/ld: note: 'pthread_cancel@@GLIBC_2.2.5' is defined in DSO
/lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
If you are expecting this app to use pthreads then -lpthread would seem
to be indicated.
