In particular, it would be useful to know which of the THIRDPARY_BUILD_ options you have switched on and whether you're using boost and zlib from Ubuntu packages or whether they're being built as part of the Nektar build.

Can you give us some more information about the environment you're working on since that will assist in trying to identify the problem. e.g. can you please provide the Linux distribution and version that you're working on, the version of Nektar++ you're trying to build and whether you've cloned from GitHub or downloaded a source tarball from the website. Can you also tell us what CMake configuration you're using.
