Don't build Record and UnitTest as shared libraries

When building the library Record.so and UnitTest.so are build, which is not needed. The CMake is updated so that they are now build as object libraries.

test/Common/CMakeLists.txt

 foreach(component Record UnitTest)
-  add_library(${component})
+  add_library(${component} OBJECT)
   target_sources(${component} PRIVATE ${component}.cc)
   target_include_directories(${component} PRIVATE ${CMAKE_SOURCE_DIR})
   target_link_libraries(${component} PUBLIC cudawrappers::cu)
