<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><br>
I am trying to control the flow of my program based on the value of a cmake variable called
</span><span lang="EN-US" style="font-family:"Lucida Console";color:red">CMAKE_SIZEOF_VOID_P</span><span lang="EN-US">.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">To start off, I wanted to just see what value this variable took under multiple different configurations, by issuing the following command in my cmakelists.txt file:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-family:"Lucida Console";color:red">message(${CMAKE_SIZEOF_VOID_P})<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-family:"Lucida Console";color:red"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This works perfectly. However, whenever I try to run the above command on my *.cmake file, I get no value returned to me (it just throws an error).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It is important that I am able to access the value of this variable in my *.cmake file, as that will help me decide what flags and other parameters to pass in to the compiler. All I really need is a way to determine whether
cmake is running a x64 compile or a 32 bit compile, so if there is any other variable (other than this one, since it is not defined in *.cmake files) that will give me this, then that would also work for my purposes.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any help would greatly be appreciated.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks,<o:p></o:p></span></p>
