This is a small library to wrap FFTW functionality useful for Open Ephys.
It is currently used by the Phase Calculator and Real-Time Coherence plugins (under development).
On Windows, Linux, and Mac, the precompiled FFTW library is included in the libs folder - no need to install it manually.
This library should be built outside of the main GUI file tree using CMake. In order to do so, it must be in a sibling directory (e.g. OEPlugins) to plugin-GUI and the GUI must have already been compiled.
See the wiki page here for build instructions.
