Issue: Configuring cereal with the -DTHREAD_SAFE=ON option will not lead to any change in the installation. Using target_compile_definitions and target_link_libraries, the cmake targets installed in PREFIX/cmake/cereal will be updated to include the definition and library for thread safety.

Issue: Configuring cereal with the -DTHREAD_SAFE=ON option will not lead to any change in the installation.
I would like to have a system install defaulting to thread safe code, but I am not sure how the best way to solve this issue looks like. One option would be to change the default value of CEREAL_THREAD_SAFE in macros.hpp; the other option would be to create cmake targets which set the relevant compiler flags. The first solution would still suffer from not having proper support for linking a threading library.
The implemented solution tries to adjust CMakeLists.txt in such a way that it does what I think it should have done all along:
Using target_compile_definitions and target_link_libraries, the cmake targets installed in PREFIX/cmake/cereal will be updated to include the definition and library for thread safety. This will result in projects using cmake to include cereal automatically using the thread safe code globally.
A third option could be to provide two different cmake targets, one for single threaded and for multi threaded targets.
