[CMake] How to differ?

[Thomas Lehmann]

Hi,

I'm new to the cmake tool trying to find out how to apply
this best to our system. Here's a problem I would like
to know how to do best:

Assume following setup:

-          /projects/libs/one

-          /projects/libs/two

-          /projects/apps/first

-          /projects/apps/two

Both application are using both libraries.
Being in /tmp/obj ....

I have  some options to prepare a build:

-          cmake /projects   (this means: intending to build all)

-          cmake /projects/libs (this means: intending to  build all libraries only)

-          cmake /projects/apps (this means: intending to build all applications)

-          cmake /projects/apps/first (this means: intending to build app "first" only)

Now the question(s):

-          Using "build all" is fine. I'm using "link_directories" for both applications.
But using the last two examples I fail with "cannot find -lone" (and two).
How can I fix this?

-          I know I could use "include_subdirectory" but then I fail with first and third
example. I will get a message like "another target with same name already exists".
Both question are relating to same.

We would like to be flexible...
Could somebody provide a little help please?

Kind Regards
Thomas
