This is not the fault of CMake. The file should actually be called libgeotif.so.2, and the symlink should be called libgeotif.so and point to libgeotif.so.2. The symlink is only used for linking, while the real file, libgeotif.so.2, will be used at runtime. This is to make it possible to have multiple versions of libgeotif installed, but only one version will be used for linking.
