<br>That fails because CMake does not support convenience libraries:<br><a href="http://www.cmake.org/Wiki/CMake_FAQ#Does_CMake_support_.22convenience.22_libraries.3F" target="_blank">http://www.cmake.org/Wiki/CMake_FAQ#Does_CMake_support_.22convenience.22_libraries.3F</a><br>
<br>You need to do this:<br><br>ADD_LIBRARY (libA A/foo.cc )<br>ADD_LIBRARY (libB B/bar.cc )<br>ADD_LIBRARY (libC A/foo.cc B/bar.cc )<br><br>I. e. list the source files for libC<br><br>Is that what you want to do?<br><font color="#888888"></font></blockquote>

</div><div>Dont you think so it will be too hectic if there are 10 folders inside folder C and each folder has around 10 C files each. then listing all will be really cumbersome. </div>

add_library(A ${A_SRCS})<br><br>Then in the higher directory, use a foreach() loop to construct a proper relative path to each source file:<br><br>foreach(fname ${A_SRCS})<br> list(APPEND C_SRCS A/${fname})<br>endforeach()<br>
