* fix find_package for fftw3
* the patch took care of moving the files
* Additional Patch to add Suffix to LibraryDepends
* fixed minsizerel and relwithdebinfo for vs cmake configs
* remove fix for minsizerel and relwithdeb info. Use global cmake mappings of these targets instead!
* added feature packages. unfortunally avx and avx2 create an ICE with Visual Studio 2017 (maybe fixed with 2019?)
* removed sse2 as default (forgot about arm...)
