FFTW3LibraryDepends.cmake missing from autotools build #332

Open 20DM opened 1 year ago

20DM commented 1 year ago

Hi,

the CMake config file appears to reference a FFTW3LibraryDepends.cmake which doesn't seem to exist:

https://github.com/FFTW/fftw3/blob/38ea230e25e69e7a3f35b957b815bac4f9aa22b0/FFTW3Config.cmake.in#L13

Is this by accident or am I missing something...?

Cheers, Chris

It's generated by the rules in CMakeLists.txt when you run cmake

.. but not when you build with autotools, which is the default. The builds are inconsistent currently as far as I can tell.

stevengj commented 1 year ago

Yes, it might be better just to omit the FFTW3Config.cmake installation from the autotools build completely.

20DM commented 1 year ago

For what it's worth, when I build FFTW with autotools (or using Homebrew) and then manually remove that include line from the FFTW3Config.cmake, I can still link against the package just fine with my separate CMake-based application.
