10.6.1. Support for Third-Party FFT libraries through Wrappers - 5.2 English - 57404

AOCL-FFTZ can provide a drop-in compatibility layer for third party FFT libraries through the Third-Party Wrappers. Currently, a wrapper for the FFTW library is supported. To enable it, set the CMake option BUILD_THIRD_PARTY_WRAPPERS=ON during build configuration.

# configure
cmake -B <build-dir> <source-dir> \
      -DBUILD_THIRD_PARTY_WRAPPERS=ON \
      -DCMAKE_INSTALL_PREFIX=<install-path> \
      [other options]

# build and install
cmake --build <build-dir> --target install
