# ROOT and O2 need different variants of fftw3, but we cannot configure fftw3
# to build both at the same time. As a workaround, configure and build one,
# then wipe out the build directory and configure and build the second one.

# First, build fftw3 (double precision), required by ROOT.

# Now reconfigure for fftw3f (single precision float), required by O2.
