Allow building against system libs instead of bundled dependencies
When DIP_BUILD_BUNDLED_DEPENDENCIES=OFF is passed to cmake, we will rely on find_package to find Eigen3, zlib, jpeg, ics and tiff libraries. The fftw_api.h header will always be used, as it's not public API that's included in the fftw3 package on ArchLinux e.g. The default for this option is still ON, i.e. this is an opt-in feature.
