- The new cmake seems to be even smarter. If we try to use env variables in the .cmake files (eg, with And's sed fixup), they are rewritten in a subsequent re-make and take much longer). Adjusting the compiler values themselves causes a full remake. On the positive side, disabling the rpath seems to mean we may not need any of this. In summary - yuck!
