  Guide me to do that. What should be the content of cmakelist file of C

  here A and B are sub folders of C

 Do you ean you are trying this but it's not working?

 ADD_LIBRARY (libA A/foo.cc )
 ADD_LIBRARY (libB B/bar.cc )
 ADD_LIBRARY (libC libA libB )

 That fails because CMake does not support convenience libraries:

 http://www.cmake.org/Wiki/CMake_FAQ#Does_CMake_support_.22convenience.22_libraries.3F

 You need to do this:

 ADD_LIBRARY (libA A/foo.cc )
 ADD_LIBRARY (libB B/bar.cc )
 ADD_LIBRARY (libC A/foo.cc B/bar.cc )

 I. e. list the source files for libC

 Is that what you want to do?


 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.
 What should be the alternative for it.


 Here's one idea, in A and B set a variable with all of the source files and
 add them to the PARENT_SCOPE.

 set(A_SRCS a.cc)
 set(A_SRCS ${A_SRCS} PARENT_SCOPE)
 add_library(A ${A_SRCS})

 Then in the higher directory, use a foreach() loop to construct a proper
 relative path to each source file:

 foreach(fname ${A_SRCS})
 list(APPEND C_SRCS A/${fname})
 endforeach()
 foreach(fname ${B_SRCS})
 list(APPEND C_SRCS B/${fname})
 endforeach()
 add_library(both ${C_SRCS})
