[Cmake] Specifying static or dynamic linking of external libraries?

[Thomas Deschamps]

Ok,

I've specified the complete name (and I had to remove all the *.so files).
I'm trying to link against  VTK static libraries.
But the thing is I had a lot of errors of this kind:
    g++ -rdynamic -g test.o  -L/usr/local/lib -lvtkCommon -lvtkRendering 
-lvtkHybrid -lvtkImaging -lvtkGraphics -lvtkFiltering -lvtkIO 
-Wl,-rpath,/usr/local/lib  -o testImagePlaneWidget
    /usr/local/lib/libvtkCommon.a(vtkDynamicLoader.o): In function 
`vtkDynamicLoader::OpenLibrary(char const *)':
    /home/users/deschamp/Tools/VTK/Common/vtkDynamicLoader.cxx:226: 
undefined reference to `dlopen'
    /usr/local/lib/libvtkCommon.a(vtkDynamicLoader.o): In function 
`vtkDynamicLoader::CloseLibrary(void *)':
    /home/users/deschamp/Tools/VTK/Common/vtkDynamicLoader.cxx:231: 
undefined reference to `dlclose'

which means that the flag CMAKE_DL_LIBS (='ldl') is not used by 
cmake.... but why?

Therefore I included it in the CMAKE_CXX_MODULE_LINK_FLAGS

But it was not included again. I decided to include it in 
CMAKE_CXX_SHLIB_LINK_FLAGS, just to see what's happening.
The result was it included "-ldl" in the command line, which means it is 
still using shared libraries linking while I am giving him only static 
libraries, strange isn't it?

Sincerely, I do not understand what is going on, and why cmake is doing 
all those things.

The final problem I have is that even with including the "-ldl" 
somewhere it is still not working, giving errors like

    /usr/local/lib/libvtkRendering.a(vtkActor.o): In function 
`vtkActor::SetMapper(vtkMapper *)':
    /home/users/deschamp/Tools/VTK/Rendering/vtkActor.cxx:529: undefined 
reference to `vtkAbstractMapper::RemoveConsumer(vtkObject *)'
    /home/users/deschamp/Tools/VTK/Rendering/vtkActor.cxx:536: undefined 
reference to `vtkAbstractMapper::AddConsumer(vtkObject *)'
    /usr/local/lib/libvtkRendering.a(vtkDataSetMapper.o): In function 
`vtkDataSetMapper::SetInput(vtkDataSet *)':
    /home/users/deschamp/Tools/VTK/Rendering/vtkDataSetMapper.cxx:47: 
undefined reference to `vtkProcessObject::SetNthInput(int, vtkDataObject *)'

Apparently it does not find any of the vtk stuff.

Does anyone has been able to compile and use the static libraries?
