Details: - When CBLAS is enabled at configure-time, BLIS now creates a monolithic cblas.h using the same flatten-header.sh script that was recently introduced for creating monolithic blis.h header files. The top-level Makefile will also install this cblas.h file into the install prefix alongside blis.h when the 'install' target is invoked. The two header files are compatible with one another. Regardless whether the user's source #includes cblas.h, both blis.h and cblas.h, or just blis.h, the user will get the CBLAS function prototypes and enums, as expected.
