CMake no longer finds OpenBLAS

Description (last modified by szhorvat (Szabolcs Horvát))

CMake is no longer finding OpenBLAS and I am not sure why.

I am using:

OpenBLAS @0.3.24 (math, science)
cmake @3.24.4 (devel)

Fully updated ports tree, no local modifications.

Test CMake project:

cmake_minimum_required(VERSION 3.24)
project(Foo)
find_package(BLAS REQUIRED)
message(STATUS BLAS found: ${BLAS_LIBRARIES})

Configure it with cmake -DBLA_VENDOR=OpenBLAS -DCMAKE_PREFIX_PATH=/opt/local. Then it shows the error Could NOT find BLAS (missing: BLAS_LIBRARIES)

This used to work not so long ago. I am not sure when it broke. It also affects building ports that link to OpenBLAS.

My system:

macOS 13.6 22G120 arm64 Xcode 15.0.1 15A507

Sad, my hack at doesn't help at least on buildbots :(

I'm not sure how it would make any difference: @ at the start of the line just means the command is not echoed to output when it is run, and - just means make will continue even if the command's exit status is nonzero.

Yes, it doesn't; here the correct fix: https://github.com/macports/macports-ports/pull/21419

The root cause of missleading patch that I've start to dig on that and achived the expected behaviour without completley tested port destroot. When it was merged, I discovered that it doesn't work and start to dig why my ugly and unexpected patch help on local machine and doesn't help on build bot.

At that investigation I've discovered the real fix for the issue which I've opened as the second PR.
