Is it possible to have 2D arrays in CMake? As far as the core syntax is concerned, it seems like only 1D arrays are supported. So far I've had to work around this issue by using a flat array and skipping over elements using foreach() with a range and step.<div>
<br></div><div>Any ideas? Thanks.<br clear="all"><div><br></div><div>---------</div><span class="HOEnZb"><font color="#888888">Robert Dailey<br>
