Subject: [PATCH] Fix "target with the same name already exists"

```
CMake Error at /__w/parPE/parPE/deps/AMICI/build/AmiciConfig.cmake:60 (add_library):
  add_library cannot create imported target "SUNDIALS::KLU" because another
  target with the same name already exists.
Call Stack (most recent call first):
  model/CMakeLists.txt:38 (find_package)


CMake Error at /__w/parPE/parPE/deps/AMICI/build/AmiciConfig.cmake:61 (target_link_libraries):
  Cannot specify link libraries for target "SUNDIALS::KLU" which is not built
  by this project.
