</div>Then don't make this plugin internal, but external instead. Because if<br>
library is missing,<br>
VM will refuse to start. In contrast, if your plugin will be in<br>
external module, then module will refuse to load<br>
if lib is missing.<br>

<br>
</div>The philosophy of CMake configurations is to be concrete and without<br>
conditionals. I.E. they should<br>
not contain "if this, do this, if that do that" , instead if you have<br>
such choice, one should make another configuration.<br>
<br>
There is no way to predict how different is platform on which you<br>
building VM from platform where it used (especially in case of unix<br>
systems and their numerous flavors). So, what is working on your OS,<br>
could not work on another. That's why i don't see a point to put<br>
conditionals in build process.<br>
<br>
In contrast, if you have a concrete configuration, which says: if you<br>
want to build me, you should have this, this and this, and if you want<br>
to use the built artifact you should have this, this and this<br>
installed, then it makes things much more predictable and<br>
straightforward.<br>
