<div>Hello.</div>
<div><br>
</div>
<div>>e.g. if you have meta-qt5 in BBLAYERS in <build>/conf/bblayers.conf, then the recipes from "dynamic-layers/qt5-layer" are used as well.</div>
<div><br>
</div>
<div>Thanks now I can see how it is expected to work.</div>
<div>My issue here now is that some dynamyc-layers/<layer> not being added to BBFILES list.</div>
<div><br>
</div>
<div>I tried '-e' switch with my build tree and here is what I can see.</div>
<div>I think this is caused by BBFILE_COLLECTIONS evaluation timing? - but I am still looking into to find the cause.</div>
<div><br>
</div>
<div>1) .conf files read</div>
<div><br>
</div>
<div>I think these are the conf files recognized by the build sytem.</div>
<div>I cansee meta-qt5 there.</div>
<div><br>

<div>2) BBFILE_COLLECTIONS</div>
<div><br>
</div>
<div>And I can see 'qt5-layer' is being added to BBFILE_COLLECTIONS, so it 'qt5-layer' folder in every dynamic-layers should be picked into BBFILE list.</div>

<br>
what that means is that recipe from the dynamic-layers/<layer> will be<br>
parsed/added *only if* <layer> is already added in your build<br>
environment. e.g. if you have meta-qt5 in BBLAYERS in<br>
<build>/conf/bblayers.conf, then the recipes from<br>
"dynamic-layers/qt5-layer" are used as well.<br>
<br>
This is mostly to allow a BSP layer to be used with as many<br>
combinations of layers as possible.<br>
