Link my shared library to another (CMAKE)

Question

Hello,

I'm currently trying to link a CXX library that I've written to a VTK, a CMake made library - to end up creating a shared library that has my code's functionality and can resolve the symbols from VTK. I need the end result to be shared because I'd need to call the library up at runtime in Java.

Please feel free to ask any questions.

Cheers.

It sounds like you need to use target_link_libraries, so a minimal CMake block might look like,

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_library(mylib SHARED sourcefile.cxx sourcefile2.cxx)
target_link_libraries(mylib vtkRendering)

This would add a shared library called mylib (libmylib.so on Linux), that links to vtkRendering (multiple libraries could be added here). Check out 'cmake --help-commands' for a full list of CMake commands.
