igraph 0.9.2

Added

• CMake package files are now installed with igraph. This allows find_package(igraph) to find igraph and detect the appropriate compilation options for projects that link to it.

Fixed

• igraph can now be used as a CMake subproject in other CMake-based projects.
• The documentaton can now be built from the release tarball.
• Configuration will no longer fail when the release tarball is extracted into a subdirectory of an unrelated git repository.
• The generated pkg-config file was incorrect when CMAKE_INSTALL_<dir> variables were absolute paths.
• On Unix-like systems, the library name is now libigraph.so.0.0.0, as it used to be for igraph 0.8 and earlier.
• Fixed a return type mismatch in parser sources, and fixed some warnings with recent versions of gcc.
• Fixed a bug in igraph_get_shortest_paths_dijkstra() and igraph_get_shortest_paths_bellman_ford() that returned incorrect results for unreachable vertices.

Other

• Improved installation instructions and tutorial.
