Hi,

I'm using CMake to build two C-based projects

The first CMake project builds several static libraries (ARM elf / eCos)
The second CMake project builds several application which do link against the static libraries produced within the first project.
However, both CMake projects are unrelated from CMake perspective.

I've not been able to find a CMake rule to tell CMake to force relinking an application of the second project when a library generated in the first project has been updated. I always need to "touch" a source file of the second project so that Make rebuilds the file and is forced to relink the application with the static libraries of the first project.

Which CMake rule should/could I use to add a dependency from the 2nd project onto an external static library (of the 1st project) ?

TIA,
Emmanuel.
