[CMake] To specify dependency to other library

[Per Rosengren]

I have two programs foo and bar.
All classes and functionality that could potentially be used by other
programs are in the library mor.
foo and bar include mor's headers and link to it.
mor will be used by other developers. foo and bar should not be
accessible by them.

In my current setup, mor, foo and bar are all separate cmake projects in
separate directories, in separate svn repositories.

My problem is that foo and bar does not have the mor files as
dependencies in the generated Makefiles, and so are not properly rebuilt
when the mor headers or library change. What would be the best solution?

mor is built and installed with
ADD_LIBRARY( mor
STATIC <mor sources> )
INSTALL( TARGETS mor
  RUNTIME DESTINATION bin
  LIBRARY DESTINATION lib
  ARCHIVE DESTINATION lib )
INSTALL(
FILES <mor headers>
DESTINATION include/mor )

foo and bar include the installed mor headers with
#include<mor/<Class>.hh>,
and they link with the cmake command
ADD_EXECUTABLE( foo foo.cpp )
TARGET_LINK_LIBRARIES( foo mor )

Below are my actual CMakeFiles.txt files.

Thank you,
Per Rosengren
