  1. ##

  2. ## Author: Hank Anderson <hank@statease.com>

  3. ## Description: Ported from OpenBLAS/Makefile.prebuild

  4. ##              This is triggered by system.cmake and runs before any of the code is built.

  5. ##              Creates config.h and Makefile.conf by first running the c_check perl script (which creates those files).

  6. ##              Next it runs f_check and appends some fortran information to the files.

  7. ##              Then it runs getarch and getarch_2nd for even more environment information.

  8. ##              Finally it builds gen_config_h for use at build time to generate config.h.
