Hi all:
I'm working on an embedded platform and building integrated software
as multimedia CE devices. And I am just started trying to introduce
CMake to replace my legacy environment constructed by many hand-written
gnu styled makefiles.
I have many components which is cross referred to each other very
complicatedly, and it really helps a lot when I started to migrate to
CMake with the benefit of automatic dependency checking.
However, my order of building is
i) build lots of libraries, called components
ii) then build final executable, called application, linking with libraries
I really felt comfort when I modified some header files in the
component directory, and makefiles generated by CMake automatically
found it, rebuild all dependent source files as well as the libraries.
However I could not make my final executable link those libraries
automatically when libraries got changed.
I used TARGET_LINK_LIBRARIES to enumerate linking libraries, also
ADD_DEPENDENCIES with these libraries.
But I still can't make it relink to a executable when those libraries
got changed, no matter it's rebuilt by makefile or replaced by some
newer revision.
Can you post some of your cmake code? This should work. I suspect that
you are not using full paths to libraries in target_link_libraries.
add_dependencies should not be needed.
