What I've done is create a Lib folder under the source folder wanting to use the lib, I copied over the lib find and header file. I added the following to CMakeLists.txt add_subdirectory(Lib) target_link_libraries (SimpleTester UnitTest) However I am seeing 2 errors: Error 1, when I run CMake I see: CMake Warning (dev) at CMakeLists.txt:6 (add_subdirectory): The source directory C:/dev/Project/UnitTestSample/Lib does not contain a CMakeLists.txt file. CMake does not support this case but it used to work accidentally and is being allowed for compatibility. Policy CMP0014 is not set: Input directories must have CMakeLists.txt. Run cmake --help-policy CMP0014 for policy details. Use the cmake_policy command to set the policy and suppress this warning. This warning is for project developers.

Could you provide a small but self-sufficient exemplary project which demonstrates what you're doing and allows for further investigation?
