As I understand it (from reading various cmake macros) is that MACRO "parameters" are not variables. They are "names of variables", they are "aliases" to variables if you wish. So when you call a macro with the parameter "someVAR" that in the macro is made to be received as "VARIABLE" then "VARIABLE" acts like a variable holding the NAME of the argument given variable (ie holding "someVAR") so then if you need to write/read someVAR you need to "dereference" VARIABLE (ie SET(${VARIABLE} "value") and not SET(VARIABLE "value")). I haven't tried but the macro parameters might be immutable themselves (like C++ references :) ) so SET(VARIABLE something) might not be supported (but then again why would you ever need such a thing). -- Mihai RUSU Email: [EMAIL PROTECTED] "Linux is obsolete" -- AST _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
