+      Features in the ELECTRODE package are dependent on code in the

+      The ELECTRODE package also requires LAPACK (and BLAS) and CMake
+      can identify their locations and pass that info to the LATTE build
+      script.  But on some systems this may cause problems when linking

+      ``USE_INTERNAL_LINALG`` in those cases to use the bundled linear
+      algebra library and work around the limitation.
