+Subject: [PATCH 1/1] CMake/FindCBLAS.cmake: search only for cblas
+
+On Gentoo, users can "eselect cblas" to choose a cblas implementation
+at runtime. Packages build against the reference cblas, but the others
+are (by design) compatible, so we can force one to take precedence at
+runtime with an ld.so.conf entry. But that only works when consumers
+link to libcblas.so. If they link directly to (say) openblas, then
+changing how libcblas.so resolves won't help.
+
+When Flint tries to find "cblas," it looks for accelerate and openblas
+before plain cblas. That runs afoul of the scheme described above. To
+remedy it, we patch the search function so that only "cblas" is
+considered. Since virtual/cblas always pulls in the reference
+implementation, there'd be no point in altering the search order to
+consider e.g. openblas after cblas.
