BUG: Cannot find OpenBLAS on Cygwin #20491
Description
Describe your issue.
While I try to use pip3 install maryam to install maryam in Cygwin, it keeps throwing the following error:
../scipy/meson.build:169:9: ERROR: Dependency "OpenBLAS" not found, tried pkgconfig and cmake
because maryam depends on scikit-learn which depends on scipy ...
Reproducing Code Example
Although I could reproduce the issue with pip3 install maryam, it is simpler to reproduce it with pip3 install scipy as follow.

$ pip3 list

SciPy/NumPy/Python version and system information
I install Cygwin in Windows 11 arm 64. For openblas, my Cygwin only has three packages: libopenblas , openblas-debuginfo, and openblas-doc with all version 0.3.25-1 . For Python, the python39 package with version 3.9.16-1 install the following python and pip:
yutta@SurfacePro9 /cygdrive/c/Users/yutta/eclipse-workspace/Maryam
$ type python3.9
python3.9 is /usr/bin/python3.9
yutta@SurfacePro9 /cygdrive/c/Users/yutta/eclipse-workspace/Maryam
$ type pip3
pip3 is hashed (/usr/bin/pip3)
