This is because static libraries are not compiled with -fPIC with cmake. I 
tried to convince them to add -fPIC to the compilation flags just like we did 
in KDE3 (and qmake), but I failed. You have to remove the use of 
static/convenience libraries in kdevelop to solve this. CMake's include 
statement is helpful for that if you want to keep some level of modularity.
