In CMake, you can get a list of all added subdirectories by using the get_property command with the DIRECTORY property. This property stores the list of all subdirectories that have been added using the add_subdirectory() command in CMake. By using the following command:
1
|
get_property(subdirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES)
|
You can store the list of all subdirectories in the variable subdirs. This variable will contain a list of all subdirectories added in the current CMake project. You can then iterate through this list to perform any operations as needed on each subdirectory.

How to programmatically access all added subdirectories in CMake?
To programmatically access all added subdirectories in CMake, you can use the SUBDIRECTORIES variable provided by CMake. This variable contains a list of all subdirectories added to the current directory using the add_subdirectory() function.
Here is an example of how you can access all added subdirectories in CMake:
1 2 3 4 5 6 7 8 9 10 11 12 |
# Add subdirectories add_subdirectory(subdir1) add_subdirectory(subdir2) add_subdirectory(subdir3) # Get the list of all added subdirectories get_property(SUBDIRECTORIES DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES) # Loop through the list of subdirectories and print each one foreach(subdir ${SUBDIRECTORIES}) message("Subdirectory: ${subdir}") endforeach() |
In this example, we first add three subdirectories using the add_subdirectory() function. Then, we use the get_property() function to get the list of all added subdirectories in the current directory. Finally, we loop through the list of subdirectories and print each one using the message() function.
You can use this approach to programmatically access all added subdirectories in CMake and perform any further processing or actions that you need.
What precautions should be taken when sharing or distributing the list of all added subdirectories in CMake?
When sharing or distributing the list of all added subdirectories in CMake, the following precautions should be taken:
- Ensure that sensitive or confidential information is not included in the list. This includes any proprietary code, personal information, or other confidential data.
- Make sure that the list is accurate and up-to-date before sharing it with others. This will help prevent confusion or errors when others are using the list.
- Consider using version control systems such as Git to track changes to the list and manage updates effectively.
- Clearly communicate any limitations or restrictions on the use of the list, such as licensing requirements or usage permissions.
- Encrypt or password protect the list if necessary to restrict access to authorized individuals only.
- Consider providing documentation or instructions on how to properly use and interpret the list to ensure that others can effectively utilize the information provided.
- Regularly review and update the list to ensure that it remains relevant and useful to those who have access to it.
How can I retrieve a list of all added subdirectories in CMake?
You can retrieve a list of all added subdirectories in CMake by using the get_property command with the DIRECTORY property. Here's an example code snippet to achieve this:
1 2 3 4 5 6 7 8 9 10 |
# Add subdirectories to your project add_subdirectory(dir1) add_subdirectory(dir2) add_subdirectory(dir3) # Get a list of all added subdirectories get_property(subdirectories DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES) # Print the list of subdirectories message("Subdirectories: ${subdirectories}") |
This code snippet adds three subdirectories dir1, dir2, and dir3 to the project, then retrieves the list of added subdirectories using the get_property command with the SUBDIRECTORIES property. Finally, it prints the list of subdirectories.
How to leverage the list of all added subdirectories in CMake for improving project organization and structure?
One way to leverage the list of all added subdirectories in CMake for improving project organization and structure is to use it to create a hierarchy of directories that reflect the logical structure of the project. This can help make the project easier to navigate and understand, as well as make it easier to maintain and update in the future.
One approach could be to create a top-level directory for each major component or module of the project, and then use the list of subdirectories to organize the files and folders within each component directory. For example, you could have a directory for your application code, a directory for third-party libraries, a directory for unit tests, etc.
You could also use the list of subdirectories to automatically generate build rules for each component or module, making it easier to build and test individual parts of the project separately. This can help reduce build times and make it easier to track down and fix bugs.
Overall, leveraging the list of all added subdirectories in CMake can help you create a more organized and maintainable project structure, making it easier to work with and collaborate on the project in the long run.
How to locate all added subdirectories in CMake?
To locate all added subdirectories in CMake, you can use the following command in your CMakeLists.txt file:
1 2 3 4 5 6 |
# List all added subdirectories get_property(subdirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES) foreach(subdir ${subdirs}) message("Added subdirectory: ${subdir}") endforeach() |
This will list all the added subdirectories in your project. You can add this code to your CMakeLists.txt file to get a list of all subdirectories that have been added using the add_subdirectory() command.
