How to Clear All Defines From Cmake?

To clear all defines from CMake, you can use the command cmake -U. This command will unset all CMake cache variables, effectively clearing all defines that have been set. This can be useful if you want to start with a clean slate and remove all previously defined variables in your CMake configuration.

How to remove all defined paths from cmake project settings?

To remove all defined paths from a CMake project settings, you can follow these steps:

1. Open the CMakeLists.txt file in your project directory.
2. Remove all the include_directories() and link_directories() commands that define the paths in the project.
3. Save the changes to the CMakeLists.txt file.
4. Delete the CMakeCache.txt file in your build directory to reset the cache.
5. Re-run CMake to regenerate the project files without the defined paths.

By following these steps, you will have successfully removed all defined paths from the CMake project settings.

How to revert all defined options to default values in cmake?

To revert all defined options to their default values in CMake, you can do the following:

1. Clear the cache of CMake by deleting the CMakeCache.txt file in the build directory.
2. Delete the entire build directory and create a new one.
3. Run CMake again to generate a new build system with the default values of all options.

Alternatively, you can manually reset the values of specific options by setting them to their default values in your CMakeLists.txt file. This can be done by using the set() function to assign the default values to the options.

Here's an example of how to reset a specific option to its default value:

1
2
3
4

option(MY_OPTION "Description of MY_OPTION" OFF)  # Default value is OFF

# Reset MY_OPTION to its default value
set(MY_OPTION OFF)

By resetting all defined options in this manner, you can rever them back to their default values in CMake.

How to reset all defined options in cmake to default values?

To reset all defined options in CMake to their default values, you can simply delete the CMakeCache.txt file that is generated by CMake.

Here are the steps to reset all defined options in CMake:

1. Navigate to the build directory where the CMakeCache.txt file is located.
2. Delete the CMakeCache.txt file.
3. Re-run CMake to regenerate the CMakeCache.txt file with default values for all options.
4. Configure and generate the project as usual.

By deleting the CMakeCache.txt file, all previously defined options will be reset to their default values, and you can start fresh with your CMake configuration.

How to clear all defines from cmake using the command line?

To clear all defines from CMake using the command line, you can use the following command:

1

cmake -U <variable_name>

Replace <variable_name> with the name of the define you want to clear. If you want to clear multiple defines, you can use this command multiple times, each time specifying a different define to clear.

Alternatively, if you want to clear all defines at once, you can delete the CMakeCache.txt file in your build directory and rerun CMake to regenerate it with no defines. This can be done using the following commands:

1
2

rm CMakeCache.txt
cmake .

This will clear all defines and start with a clean slate for CMake to configure your project.

What is the easiest way to clear all defines from cmake files?

The easiest way to clear all defines from CMake files is to delete the CMakeCache.txt file. This file stores all the defines and cache variables set during the configuration process. By deleting this file, you can start fresh with a clean slate of defines in your CMake files.

You can delete the CMakeCache.txt file by locating it in your CMake build directory and either deleting it manually or running the following command in your terminal:

1

rm CMakeCache.txt

After deleting the CMakeCache.txt file, you will need to reconfigure your project by running CMake again to regenerate the cache and define new variables as needed.

How to clear all defined targets from cmake build scripts?

To clear all defined targets from a CMake build script, you can use the cmake command with the -E flag and the remove_directory function to delete the build directory. This will effectively clear all previously defined targets and start fresh.

Here is an example command to clear all defined targets:

1

cmake -E remove_directory build

This command will remove the entire build directory, including all targets and build artifacts. Make sure to replace build with the name of your build directory if it is different.

After running this command, you can re-run your CMake build scripts to define new targets and build your project again from scratch.
