Openblas support on Macosx M1 #1171
Description
Hello,
I currently struggle with an ugly yet familiar issue, the library cannot load :
UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path:
I managed to install openblas to the current "stable" version supported by Javacpp presets : 0.3.19, with javaCPP 1.5.7.
With the example code, at version 1.5.7, I get this error (which may not be exactly the same) :
LAPACKE_dgels (row-major, high-level) Example Program Results
[WARNING]
java.lang.UnsatisfiedLinkError: 'int org.bytedeco.openblas.global.openblas.LAPACKE_dgels(int, byte, int, int, int, double[], int, double[], int)'

I use Java 17 and want to work with OpenCV in Processing 4 on my Mac. By default Opencv 4.5.5 on OSX comes with Openblas 0.3.20.
The Openblas_nolapack code does have any macosx-arm64 specific code, so maybe it fails at loading some dependencies ?
It is / was reported to work on OSX there #1069 . I saw the other issues with Openblas there bytedeco/javacv#1435, I guess it is not an easy dependency to work with.
Do you have an idea to solve this ?
Cheers,
Jeremy.
