<font face="Helvetica, Arial, sans-serif">Hi cmake users:<br>
<br>
</font><font face="Helvetica, Arial, sans-serif">I am trying to use
cmake to define a symbol so that I can use the #if syntax in C++.<br>
<br>
I have read the documentation for the </font><font
face="Helvetica, Arial, sans-serif">SET_TARGET_PROPERTIES command and
it seems to me that there is a property called </font><font
face="Helvetica, Arial, sans-serif">DEFINE_SYMBOL which sets "... <i>a
symbol that is defined when compiling C or C++ sources</i>"
(<a class="moz-txt-link-freetext"
href="http://www.cmake.org/HTML/Documentation.html">http://www.cmake.org/HTML/Documentation.html</a>).
However, when I use
this property it does <b>not </b>define the symbol. I am using CMake
v2.2.3 with Microsoft Visual Studio 7 .NET 2003 on a Win32 machine. <br>
<br>
FYI I can get the LINK_FLAGS property to work, but not the
DEFINE_SYMBOL... <br>
<br>
Have I misunderstood something? Am I setting the property correctly?
Any help would be appreciated. My cmake file and source is below:<br>
