## Description: Ported from the OpenBLAS/c_check perl script.
|
|
## This is triggered by prebuild.cmake and runs before any of the code is built.
|
|
## Creates config.h and Makefile.conf.

# N.B. c_check is not cross-platform, so instead try to use CMake variables. Alternatively, could use try_compile to get some of this info the same way c_check does.
