[CMake] Generating shared libraries on Visual 8.0

[Stefan Buschmann]

How do you create those libraries in your CMakeLists.txt? To build a 
shared library, you usually only need to specify "SHARED" when calling 
ADD_LIBRARY, e.g.
  ADD_LIBRARY(MyProject SHARED ${PROJECT_SOURCES})

If you want to decide whether to build static or dynamic libraries based 
on a variable, I would use something like this (this could of course be 
simplified):
  IF (SHARED_LIBRARIES)
    ADD_LIBRARY(MyProject SHARED ${PROJECT_SOURCES})
  ELSE (SHARED_LIBRARIES)
    ADD_LIBRARY(MyProject ${PROJECT_SOURCES})
  ENDIF (SHARED_LIBRARIES)
