[CMake] Correct usage of add_library

[Cedric Doucet]

Hello,

thank you very much, it works fine!

Do you know how to create a target so that

   make mykernel

creates a library libkernel.so?


For the moment, I create a library with the command

   add_library(kernel SHARED ${src})

and I build libkernel.so by typing make.

I have found there exists a command add_custom_target but I don't know how to use it.
I tried

   add_custom_target(mykernel DEPENDS kernel)

but it does not seems to take my include_directories instructions into account since some headers are not found anymore (they're found when I type 'make').
