`undefined symbol: fftwf_execute` when loading pitch_scale plugin in Carla

[v1993]

I'm using a version of plugins from Ubuntu package in case that's relevant. Trying to load LV2 version of Higher Quality Pitch Shifter results in this error:

LADSPA version loads without issues.

[swh]

What host is that error coming from, and is it the same host that loads of the LADSPA version OK?

[v1993]

It's Carla Plugin Host. Yes, it has support both for LV2 and LADSPA and loads LADSPA version fine.

[v1993]

Additionally:

v@v-home:~$ ldd /usr/lib/lv2/pitch_scale-swh.lv2/plugin-linux.so
	linux-vdso.so.1 (0x00007ffe0f9c3000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fc7e4117000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc7e3e00000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fc7e4494000)

So it appears that plugin is for some reason neither statically nor dynamically linked to libfftw. Should I report this issue to package maintainers instead?

[swh]

I think so yes, it looks like there's some linked flags missing.

I remember FFTW being a bit complex.
