Unable to require fftw.cr

[Vici37]

Hello! Thanks for creating these bindings!

I don't know if you've used them in another project yet, or just created them for the fun of it. I've written my own implementation of FFT in crystal and was interested in benchmarking it against FFTW, but have run into an error whenever I require it due to this crystal compiler error: crystal-lang/crystal#8665 .

Essentially, the compiler is trying to treat the fftw.cr directory as a file when requiring things, and then fails when it discovers it's a directory.

Error: while requiring "[MY_TOP_LEVEL_REQUIRE_INCLUDING_FFTW.CR]"                                                              
Error: Error reading file: Is a directory

Creating an empty project that only includes this dependency triggers a full on compiler error 😬

Any suggestions on how to include these bindings correctly?
