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

Drescher > -- John thanks, I was able to get a DLL built, now I have a program that want to link against the lib and use the DLL. 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. Use -Wno-dev to suppress it. -- Configuring done -- Generating done -- Build files have been written to: C:/dev/Project/UnitTestSample/build == Error 2 When I build I get a link error, which I fix by copying over the lib file into the build folder. How can I tell the linker from CMake where to find the lib? LINK : fatal error LNK1104: cannot open file 'UnitTest.lib' LINK Pass 1 failed. with 2 NMAKE : fatal error U1077: '"C:\Program Files\CMake 2.8\bin\cmake.exe"' : return code '0x' Stop.
