Dear all,
I'm having difficulty making CMake find any BLAS on my macOS. I have two:
1. OpenBLAS installed with homebrew:
/usr/local/opt/openblas/lib/libopenblasp-r0.2.19.dylib
2. System
BLAS:
/System/Library/Frameworks/Accelerate.framework//Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib
For (1.), I set BLA_VENDOR "OpenBLAS" as per the docs of FindBLAS.cmake.
CMake fails with *"A required library with BLAS API not found. Please
specify library location." *I fixed it with a kludge by
- set(_libdir "/usr/local/opt/openblas/lib" CACHE INTERNAL "OpenBLAS
location")
in the cache before calling FindBLAS. This violates all kinds of
principles, among which the fact that ${_libdir} is a local variable to the
FindBLAS module.
For (2.), FindBLAS actually finds something, however, the ${BLAS_LIBRARIES}
variable is set to *"/System/Library/Frameworks/Accelerate.framework"* which
is a folder and thus unusable in any IMPORTED targets.
Any advice? I did not find anything related in the open "FindBLAS" issues
on Gitlab.
Best regards,
Robin
