While building on Windows using emerge I didn't see this though.</p></pre>

All of frameworks compiled with no changes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Thank you for taking the time to look at this.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I am now running with :<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />

cmake version 2.8.12.2</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It might be worth noting that with the changes in this patch cmake 2.8.12.2 was able to compile frameworks all the way to KHTML with no complaints. Clearly, I am a cmake novice, but if this patch doesn't break the build with 3.0 and it makes it possible to build it with 2.8.12.2 it might make the overall build more robust.</p>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Steps to Replicate the Problem:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
1. Delete the existing header files for KCoreAddons and the existing build files.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
rm -r $KF5/KcoreAddons<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
rm -r <your kcoreaddons/build directory><br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
2. Re-build kcoreaddons from a new build dir<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
cmake -DCMAKE_INSTALL_PREFIX=$KF5 ..<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
3. Check in $KF5/KcoreAddons and there should only be these headers:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
KAboutData kaboutdata.h kcoreaddons_export.h</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Solution:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
This patch solves the problem by changing the name of var2 to KCoreAddons_HEADERS_lowercase and exporting both KCoreAddons_HEADERS and KCoreAddons_HEADERS_lowercase.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Extended Solution:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
If this patch is approved, then I will <br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
1. Submit patches to the other frameworks using ecm_generate_headers() in this fashion.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
2. submit a patch to extra-cmake-modules to warn when var1 and var2 have the same name. </p></pre>
