To add a .obj file to the dependencies with CMake, you can utilize the add_custom_command and add_custom_target functions in your CMakeLists.txt file. First, you will need to use add_custom_command to create a command that copies the .obj file to the build directory during the build process. Next, you can use add_custom_target to ensure that this command is executed before the build target is built. This will ensure that the .obj file is present in the build directory and can be used as a dependency for your project.

What is the best practice for including .obj files in CMake projects?
The best practice for including .obj files in CMake projects is to use the add_library() command to create a library from the .obj files and then link that library to the target executable. Here is an example:
1 2 3 4 5 6 7 8 |
# Create a library from the .obj files add_library(my_library OBJECT file1.obj file2.obj) # Create executable target add_executable(my_target main.cpp) # Link the library to the executable target_link_libraries(my_target PRIVATE my_library) |
By using the add_library() command with the OBJECT keyword, CMake will build the .obj files as part of the project and link them to the target executable. This approach ensures that the .obj files are included in the build process and dependencies are managed correctly.
How to configure CMake to recognize and include .obj files?
To configure CMake to recognize and include .obj files, you can use CMake's target_sources command to add the .obj files to your project. Here's how you can do it:
- Open your CMakeLists.txt file in your project.
- Use the target_sources command to specify the .obj files you want to include. This command adds source files to the specified target.
Example:
1 2 3 |
target_sources(your_target_name PRIVATE path/to/your/file.obj ) |
- Replace "your_target_name" with the name of the target you want to add the .obj file to.
- Replace "path/to/your/file.obj" with the path to your .obj file. This can be an absolute or relative path.
- Save your changes to the CMakeLists.txt file and re-run CMake to generate the build files.
By following these steps, you can configure CMake to recognize and include .obj files in your project during the build process.
What is the connection between .obj files and CMake configurations?
CMake is a build configuration tool used to generate project files for build systems such as Makefiles or IDE projects. .obj files are object files generated by the compiler during the compilation of source code.
The connection between .obj files and CMake configurations lies in the build process. When using CMake to configure a project, it specifies how the project should be built, including compiler options, include directories, and output directories. When the project is built using CMake, it compiles the source code files into .obj files and links them together to create the final executable or library.
In summary, .obj files are generated during the build process, and CMake configurations specify how the project should be built, including how .obj files are generated and linked together.
