<p class=MsoNormal>I have a project set up that imports libraries, and I want
to relink if those imported libraries change;<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For example, in a directory I have<o:p></o:p></p>
<p class=MsoNormal>hellow.c<o:p></o:p></p>
<p class=MsoNormal>libfred.a<o:p></o:p></p>
<p class=MsoNormal>CMakeLists.txt<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>where CMakeLists.txt contains:<o:p></o:p></p>
<p class=MsoNormal>-----------------------------------------<o:p></o:p></p>
<p class=MsoNormal>LINK_DIRECTORIES(.)<o:p></o:p></p>
<p class=MsoNormal>ADD_EXECUTABLE(hellow hellow.c)<o:p></o:p></p>
<p class=MsoNormal>TARGET_LINK_LIBRARIES(hellow fred)<o:p></o:p></p>
<p class=MsoNormal>-----------------------------------------<o:p></o:p></p>
<p class=MsoNormal>I run 'cmake .'<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Now if I touch hellow.c, hellow rebuilds, but if I touch
libfred.a then hellow doesn't rebuild.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I've tried every method I can think of to add a dependency
from the executable on the library, but I can't work out how to do it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>One trick that I have found, which is unsatisfying in many
ways, is:<o:p></o:p></p>
