Apparently, they are not considered variables and are used directly as strings.
However, if their contents can be construed as variables themselves (even though it is not desired), we have a problem when the only way to perform the test is to create another explicit variable assigning it to what the macro argument contains. The problem doesn't appear to pertain to functions. Steps to Reproduce: Please use the attached CMakeLists.txt file with "cmake -Wno-dev .". Additional Information: It would really be a good idea to create a version of if/elseif/else/endif which does NOT attempt to treat its arguments as variables, either by creating a new name for the command or, better yet, by adding a new policy (possibly not associated with a version yet). Otherwise, when trying to compare things which might be variables but should not be treated as such for the purposes of the comparison, one runs into subtle problems (when checks "randomly" fail) or has to create a level of indirection, by setting a new variable just for that. I am sure you've heard this all before. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2011-08-12 08:13 freddie New Issue 2011-08-12 08:13 freddie File Added: CMakeLists.txt ====================================================================== _______________________________________________ cmake-developers mailing list [email protected] http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
