In CMake, you can define the output directory of coverage files by setting the CMAKE_BINARY_DIR variable. By default, coverage files generated by tools like Gcov or Lcov are stored in the same directory as the compiled binaries. However, you can specify a different output directory by setting the CMAKE_BINARY_DIR variable to the desired location.

To run a specific unit test using "make" with CMake, you first need to add a new target for the specific unit test in your CMakeLists.txt file. This target should include the executable for the unit test along with any dependencies it may have.Once you have added the target in CMakeLists.txt, you can then use the "make" command in the terminal to build the target and generate the executable for the specific unit test.

To get the target install location from CMake, you can use the CMAKE_INSTALL_PREFIX variable. This variable is typically set by the user or the build system to specify the installation directory for the target. You can access this variable in your CMakeLists.txt file to determine where the target should be installed. Additionally, you can use the INSTALL command in CMake to specify the target install location directly within your build script.

To use a dynamic link library (DLL) with CMake, you first need to ensure that the appropriate DLL file is available on your system. Then, in your CMakeLists.txt file, you can use the find_library() command to locate the DLL file. Once the DLL has been located, you can use the target_link_libraries() command to link the DLL with your project.For example: find_library(library_name NAMES library_name.

To show file download progress with CMake, you can use the file(DOWNLOAD ...) command to download a file from a URL. To display the download progress, you can use the set(FILE_NAME_PROGRESS ...) command to set a variable that tracks the progress of the download. You can then use this variable to display the progress in your CMake scripts or use it to update a progress bar in your application.How to handle errors while showing file download progress with cmake.

To compile C++ as CUDA using CMake, you need to modify your CMakeLists.txt file to include the necessary CUDA compiler options and link against CUDA libraries. You can specify the CUDA compiler using the CMAKE_CUDA_COMPILER variable. Additionally, you can set the CUDA architecture using the CUDA_ARCHITECTURES variable to specify the compute capability of your GPU.

To create a plug-in registry using CMake, you will need to define a structure that keeps track of all the plug-ins in your system. This could be a simple data structure like a map or a list that associates each plug-in name with its corresponding file path.When you build your plug-ins with CMake, you can add custom commands that will register each plug-in into your registry.

To link static libraries in CMake, you need to add the library's path to the target_link_libraries function in your CMakeLists.txt file. First, use the find_library command to locate the library file on the system. Then, add the library file path to the target_link_libraries function along with the name of the target you want to link the library to. Finally, rerun CMake to generate the build system with the new library linked to your target.

To get a relative path for CMake unit tests, you can use the CMake built-in variable ${CMAKE_CURRENT_SOURCE_DIR} which represents the directory where the currently processed CMakeLists.txt file is located. You can use this variable to specify the relative path to your test files in the add_test command. By using relative paths, you can ensure that your tests are easily portable and can be run from different build directories.

To remove or disable a target in CMake, you can use the set_target_properties command with the EXCLUDE_FROM_ALL property set to TRUE. This property ensures that the target is not included in the default build target. Additionally, you can use the INSTALL property to prevent the target from being installed when the install target is run. By setting these properties appropriately, you can effectively remove or disable a target in CMake.How to remove a specific source file from a target in CMake.
