<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Given that add_library() produces a unique filename per platform (the “<span style="color:black">actual file name of the library built is constructed based on conventions of the native platform (such as
<span class="pre"><span style="background:#ECF0F3">lib<name>.a</span></span> or<span class="pre"><span style="background:#ECF0F3"><name>.lib”</span></span>), how does one add the library to the final application without having to deal with the filename difference?
In other words, I’ve got one library that, by default, produces ‘libtest.a’ on Linux and ‘test.lib’ on Windows. How can I add this imported library into the final application in a cross platform manner? I know I can specify two different imported locations
(see below), but it seems odd to me that Cmake – the cross-platform build env generator – doesn’t have a better native way of dealing with this….<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">The snippet below will work, but just seems wrong given the nature of what CMake is intended to do…is there a better way that I’m missing?! If not, can I request that a future release of Cmake handle platform
naming convention difference internally when invoking ADD_LIBRARY with the IMPORTED tag set? Ok so, to be fair, Cmake can be used to cross compile and that certainly complicates my feature request but, when not cross compiling, CMake knows what platform it’s
being executed on so it should be able to resolve static archive platform decorations internally.<o:p></o:p></span></p>
