Re: [CMake] Problem with SET_TARGET_PROPERTIES DEFINE_SYMBOL property

[Dan Mueller]

Thanks for your suggestion Filipe. In my original email I didn't make it very clear that I have multiple targets and I only want to add a symbol definition for a specific target. From my understanding (and testing) the command ADD_DEFINITIONS adds a definition for all targets in the project. I've decided to use CONFIGURE_FILE and explicitly declare #define ${MY_SYMBOL} which will be filled in at configuration time (rather than build time). Thanks everyone.

I have read the documentation for the SET_TARGET_PROPERTIES command and it seems to me that there is a property called DEFINE_SYMBOL which sets "... /a symbol that is defined when compiling C or C++ sources/" (http://www.cmake.org/HTML/Documentation.html). However, when I use this property it does *not *define the symbol. I am using CMake v2.2.3 with Microsoft Visual Studio 7 .NET 2003 on a Win32 machine. FYI I can get the LINK_FLAGS property to work, but not the DEFINE_SYMBOL... Have I misunderstood something? Am I setting the property correctly? Any help would be appreciated.
