How to Remove/Delete A Cmake Target?

To remove or delete a CMake target, you can use the command "remove_target()". This command takes the target name as an argument and removes it from the build system. This can be useful if you want to clean up your CMake project and remove unnecessary targets. Alternatively, you can also remove a target by using the "remove_executable()" or "remove_library()" commands, depending on the type of target you want to delete. Make sure to re-run CMake after making changes to update the build system.

How to delete a cmake target from the CMakeLists.txt file?

To delete a CMake target from the CMakeLists.txt file, you can simply remove the commands related to that target from the file. Here are the steps you can follow:

1. Open the CMakeLists.txt file in a text editor or an IDE.
2. Search for the commands related to the target you want to delete. These commands typically include add_executable() or add_library() followed by the name of the target.
3. Remove the commands related to the target, including any target_link_libraries(), target_include_directories(), or other related commands.
4. Save the CMakeLists.txt file.
5. Regenerate the build files by running CMake again.

After following these steps, the target should be removed from the build system and will no longer be built when you compile your project.

What is the syntax for removing a cmake target in CMakeLists.txt?

To remove a CMake target in CMakeLists.txt, you can use the remove_target() command followed by the name of the target. Here is an example:

1
2

# Remove the target "my_target"
remove_target(my_target)

You can also remove a target using the remove_executable(), remove_library(), or remove_custom_target() commands depending on the type of target you want to remove.

How to remove a cmake target using the command line?

To remove a CMake target using the command line, you can use the following steps:

1. Open a terminal or command prompt.
2. Navigate to the build directory of your CMake project.
3. Run the following command to remove the target: make clean Replace with the name of the target you want to remove.
4. This will remove the target and any associated files or build artifacts from the build directory.

Alternatively, you can also remove a target by using the cmake --build command with the --target option:

1

cmake --build . --target <target name> --clean

Replace <target name> with the name of the target you want to remove.

Remember to reconfigure and rebuild your project after removing the target to ensure the changes take effect.

How to uninstall a cmake target in MacOS?

To uninstall a CMake target in MacOS, you can use the following steps:

1. Navigate to the build directory where the target was built. This is typically the directory where you ran the cmake and make commands.
2. Use the make uninstall command to remove the target. If the target was installed using make install, running make uninstall will remove the target from the system.
3. If the make uninstall command does not work, you can manually remove the target files from the installation directory. The installation directory is usually specified in the CMakeLists.txt file or passed as a parameter to the cmake command.
4. Once you have removed the target files, you can also remove any generated CMake cache files and re-run the cmmake and make commands to rebuild the project without the target.

By following these steps, you should be able to successfully uninstall a CMake target in MacOS.

What is the best way to remove a cmake target without causing issues?

To remove a CMake target without causing issues, you can follow these steps:

1. Locate the CMakeLists.txt file in your project directory.
2. Search for the target that you want to remove in the CMakeLists.txt file.
3. Remove the lines of code related to the target you want to remove. This usually includes the add_executable() or add_library() function calls that define the target.
4. Save the changes to the CMakeLists.txt file.
5. Delete the build directory (typically a directory named "build" or "cmake-build-debug") to ensure that the changes are applied correctly.
6. Re-run CMake to regenerate the build files using the modified CMakeLists.txt.

By following these steps, you can safely remove a CMake target from your project without causing any issues. Make sure to double-check that the removed target is no longer being referenced in any other parts of your project to avoid any potential conflicts.
