[CMake] call already made makefile

[mina adel]

Thank you so much for your help

I have another problem, I have successfully created all the 3rd-party libraries.
I used ADD_CUSTOM_COMMAND to call the makefiles that are provided using these 
libraries.

Now, I want to combine all these libraries to one library. I will link against 
this library later.
I have searched google and cmake wiki. it seems that there is no straight 
forward way to do that.

one suggested using ar command to combine the files.

what is the vest way to merge all these libraries in one library.

Thanks
Mina

I assume from the context you mean make rather than cmake above.

To run make (or any command) at run-time, use the combination of
add_custom_command and add_custom_target.  Basically,
add_custom_command creates an OUTPUT file (say your library) at run
time, and add_custom_target file-depends on that file and creates a
CMake target corresponding to the custom command which you can add as
a dependency of your application target.  This insures make will be run (if
the library is not up to date) before your application is built.

Note the above is a reasonable interim measure to get you started, but
I predict that once you become more familiar with cmake you will find
that you will want to also build the library with cmake to completely
get rid of your autotools chains.  :-)
