I've updated the docs to include information about when the search is repeated and when it is not. I didn't use the exact wording but the information is there. Also, note that the commands do not load the variables directly from the cache and does not treat them specially. They basically do this: IF(NOT VAR) <try to find something> SET(VAR "result of find or <VAR>-NOTFOUND" CACHE <findtype> <docstring>) ENDIF(NOT VAR) -Brad _______________________________________________ CMake mailing list [email protected] http://www.cmake.org/mailman/listinfo/cmake
