[CMake] a question about archiving libraries

[mina adel]

Hi,
Thank you so much for your reply.

About archiving the libraries, can I use "ar" with "custom_command()" to archive 
the three libraries into one big library.?

Thank you in advance
Mina

You should have a look at:
ExternalProject_Add from the ExternalProject CMake module.

You don't, at least not 'out of the box' with CMake.
If you know how to do that by "hand" then you can craft a custom
commande to do it.

You are looking for something like "Convenience library" which are not
supported by CMake:
http://www.cmake.org/Wiki/CMake_FAQ#Does_CMake_support_.22convenience.22_libraries.3F


Now if your 3 libs (amd btf colamd) are "just" a set of file to compile
then may be creating a add_library CMake rule which is the collation
of all sources
in there may be a solution.
