<p style="margin-top:0;margin-bottom:0">Hey folks,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I am trying to compile VTK with ANGLE on Windows. (for those who don't know, ANGLE is a GLESv2 and GLESv3 front-end over DirectX).</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">And I am using VTK in a Qt app.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Since Qt already ships with ANGLE (dll, import library, headers, everything I need), I am trying to use this library (libglesv2.lib) instead of the native opengl32.lib, which loads the native OpenGL driver DLL.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">However, I am hitting problems everywhere. </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Doing research on the topic, it appears that someone successfully managed - sort of - to get this going in 2017.</p>

<p style="margin-top:0;margin-bottom:0">Alas, the suggested patch file to the cmake files no longer seems relevant.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Also, as as late, there seems to be new difficulties with doing this, although the post below is with Linux. </p>
