While installing from source I get the message:

fftw.c:17:10: fatal error: fftw3.h: No such file or directory
 #include <fftw3.h>
          ^~~~~~~~~
compilation terminated.
make: *** [C:/R/R-4.1.2/etc/x64/Makeconf:238: fftw.o] Error 1
ERROR: compilation failed for package 'fftw'

Please advise, thank you!
