Stefan,

We are not specifying anything when doing ADD_LIBRARY. We are using the 
BUILD_SHARED_LIBS variable instead. This variable is set to SHARED or 
STATIC in our root CMakeLists.txt depending on what the user choosed in 
the cmake gui.

In our "Mastering CMake" book, it is said that if you do not specify 
anything in ADD_LIBRARY, then it uses the BUILD_SHARED_LIBS variable to 
determine if it should build static or shared libraries. Should we set 
this variable to SHARED/STATIC or to 1/0 as it is recommended in cmake 
2.6 online documentation ? Maybe we did misread the book as we are 
setting BUILD_SHARED_LIBS to SHARED or STATIC. The strange thing is that 
it is working fine on linux-like OS ...
