<p class="MsoNormal">Specifically, I’m getting the following error:<o:p></o:p></p>

<p class="MsoNormal">Has anyone seen this before? Looking at CMakeCInformation.cmake:37, it looks like it couldn’t find the compiler, which makes me suspect the ‘-GXcode’ isn’t being handled properly. Does CMake require a space there?<o:p></o:p></p>
