Cmake include subdirectories7/24/2023 ![]() Target_link_libraries(prj PackageName::Libraries) I am wondering if this is a valid pattern below? find_package(PackageName) This means I will compile a lot of dependencies my self. Ultimately I would like to be able to do find my dependencies in the CMAKE_INSTALL_PREFIX and make sure to have reproducible builds and not use system libraries. ![]() Path you chose for “Where to build the binaries” in the GUI.I’m having trouble distinguishing the best way to include dependencies. the directory in which you ran the cmake command or the This variable holds the path to the top level binary output directory, If you add a directory that isn’t a subdirectory you need to specify the Output directory should be, making the second argument optional. The current directory CMake will automatically determine what the binary When adding a directory that is a subdirectory of Project with binary_dir as its correspondingīinary output directory. We fix this by telling GTest to use its ownĪdd the directory source_dir to the current Not present in the C++11 standard library that Apple uses so GTest cannotįind it and won’t compile. Tuple class from the draft TR1 standard and therefore looks for Using a different standard library that fully supports C++11. The second problem occurs on newer version of Mac OS X which default to Microsoft C/C++ Compiler Run-Time Library. Google Test to use the DLL-specific version to match Visual Studio’s defaultīy setting the gtest_force_shared_crt option to Output a large number of errors since we would be linking against twoĭifferent copies of the standard library. Then when our test links againstīoth toDoCore and gmock_main the linker will Byĭefault Google Test overrides this so that the non-DLL version of the When building static libraries, CMake’s default, MSVC defaults to linkingĪgainst the multi-threaded, DLL-specific version of the standard library. When using Visual Studio to build our test we would run into a problem. We don’t just add the Google Mock directory, we also work around Worry about those later, for now it’s good enough. There are several potential problems with that line but we will The path to Google Mock is stored in a cached variable so that you canĮasily set it to the correct value either from the command line or via one There were some minor changes to the C++, grab the files here:Ĭmake_minimum_required ( VERSION 2.8 FATAL_ERROR ) set ( CMAKE_LEGACY_CYGWIN_WIN32 0 ) project ( "To Do List" ) enable_testing () if ( "$ /include ) add_executable ( ToDoTest ) target_link_libraries ( ToDoTest toDoCore gmock_main ) add_test ( ToDoTest ToDoTest )įirst we add the Google Mock directory to our project then we add our If we had a collection of classes instead of just one. Unit test, and perhaps a GUI App it would be compiled three times. So if the ToDo class is used by our command line tool, a CMake will compile source files once for each target Though it is a single source file making it a library actually has one We will make the ToDo class its own library, and put it in a subdirectory. Google Mock to add a more realistic unit test. In this chapter we will split up our project to have a library which we can Let’s add subdirectories, libraries,Īnd proper unit tests to make our project more realistic. ![]() A real project would be moreĬomplicated than the one we’ve created.
