<br>
Using target_link_libraries() on the imported lib does not work because "it is not built".<br>
<br>
So the question remains open : how to represent include and link dependencies between 2 imported libs ?<br>
<br>
With regards,<br>

PS : as to why I had to have 2 stages (A_imported and A), this is because I wanted to add an alias which is not possible on an imported target<br><br><div class="gmail_quote">Le 7 avril 2017 12:32:52 GMT+01:00, David Jobet <david.jobet@free.fr> a écrit :<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Well not quite.<br />
I tried that, but my current definition is rather<br />
Target_link_libraries(B interface B_imported)<br />
<br />
I don't remember for which reason I had to do it in 2 stages like that (the A/A_imported and B/B_imported versions)<br />
<br />
If I add A in the list to read :<br />
Target_link_libraries(B interface B_imported A)<br />
<br />
Then linking against B does add B_imported and A, but it does not keep the link order and might put B_imported before A on the command line.<br />
<br />
I'll try with property INTERFACE_LINK_LIBRARIES instead, and will also try to remove those 2 stages...<br />
<br />
With regards<br />

<b>Subject:</b> [CMake] Transitive include and link libraries on imported targets ?<p></p></span></p>
<p class="MsoNormal"></p><p> </p>
<p class="MsoNormal">Hello,<br />
<br />
Let's say I build some external libs A and B with B depending on A.<br />
B and A do not use cmake, so I build them and install them in a 3rdparty directory. I now have access to includes and libs.<br />
I then create some cmake file to describe those libs so I can use them in my project :<br />
Add_library(A_imported STATIC imported)<br />
Set_property(TARGET A_imported APPEND PROPERTY INTERFACE_INCLUDE_DIRECTORIES 3rdparty/include/A)<br />
Set_property(TARGET A_imported APPEND PROPERTY IMPORTED_LOCATION 3rdparty/libs/libA.a)<br />
Add_library(A INTERFACE)<br />
Target_link_library(A INTERFACE A_imported)<br />
<br />
Same thing for B<br />
<br />
Now let's say I create a top-level target T that depends on B. Compilation might fail because B might include files from A and A is currently not a dependency of T.<br />
<br />
I can fix it in 2 ways :<br />
1- add A as a dependency of T, but I will need to do it on all my Ts<br />
2- somehow make B have transitive dependencies for include and link on A. That would be my prefered choice... But I don't know how to do it.<br />
<br />
Is it possible ? How ?<br />
<br />
Tx for your help.<br />
<br />
David</p><p></p>
