How to Get A List Of All Added Subdirectories In Cmake?

To get a list of all added subdirectories in CMake, you can use the get_property command to retrieve the SUBDIRS property. This property contains a list of all subdirectories that have been added using the add_subdirectory command in your CMakeLists.txt file. By retrieving this property, you can access the list of all added subdirectories and use it for further processing or manipulation within your CMake script.

How to export a list of all added subdirectories in CMake to a file?

You can export a list of all added subdirectories in CMake to a file by using the get_property command to retrieve the list of subdirectories and then writing it to a file using the file command.

Here's an example CMake code snippet that demonstrates how to export the list of added subdirectories to a file named subdirectories.txt:

1
2
3
4
5
6
7
8

# Get the list of added subdirectories
get_property(subdirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES)

# Write the list of subdirectories to a file
file(WRITE subdirectories.txt "")
foreach(subdir ${subdirs})
  file(APPEND subdirectories.txt "${subdir}\n")
endforeach()

This code snippet first retrieves the list of added subdirectories using the get_property command with the SUBDIRECTORIES property. It then loops through each subdirectory and appends it to the subdirectories.txt file using the file command with the WRITE and APPEND options.

After running the CMake code above, you can find a file named subdirectories.txt in the build directory containing the list of added subdirectories.

What is the easiest way to get a list of all added subdirectories in CMake?

One way to get a list of all added subdirectories in CMake is by using the get_property command along with the SUBDIRECTORIES property.

Here is an example code snippet that demonstrates how to get a list of all added subdirectories:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

# Add subdirectories in your CMakeLists.txt file
add_subdirectory(subdir1)
add_subdirectory(subdir2)
add_subdirectory(subdir3)

# Get a list of all added subdirectories
get_property(subdirs GLOBAL PROPERTY SUBDIRECTORIES)

# Print the list of subdirectories
message("List of subdirectories: ${subdirs}")

In this example, after adding the subdirectories subdir1, subdir2, and subdir3, the get_property command is used to retrieve the list of all added subdirectories. The retrieved list is then printed using the message command.

How can I retrieve a list of all subdirectories added to CMake?

You can retrieve a list of all subdirectories added to CMake by using the get_property command with the SUBDIRECTORIES property. Here is an example command to retrieve a list of all subdirectories added to CMake:

1
2

get_property(subdirs DIRECTORY ${CMAKE_SOURCE_DIR} PROPERTY SUBDIRECTORIES)
message("Subdirectories: ${subdirs}")

This command will return a list of all subdirectories added to CMake in the current CMakeLists.txt file. You can adjust the DIRECTORY parameter to specify a different directory if needed.

What is the correct approach for obtaining a list of all subdirectories added to CMake?

To obtain a list of all subdirectories added to CMake, you can use the get_property command with the DIRECTORY option. This command returns the list of subdirectories added with the add_subdirectory command in the current directory.

Here is the correct approach:

1
2

get_property(subdirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES)
message("Subdirectories added to CMake: ${subdirs}")

This will output the list of all subdirectories added to CMake in the current directory.

How do I extract a list of all added subdirectories from CMake configuration files?

To extract a list of all added subdirectories from CMake configuration files, you can use the following regular expression in a text editor or command line tool:

1

add_subdirectory\(([^)]+)

This regex pattern will match the add_subdirectory() function calls in CMake configuration files and capture the directory name specified within the parentheses. You can then use a regex search functionality in your text editor or command line tool to find and extract all the subdirectories added in the CMake configuration files.

What is a simple way to list all subdirectories added in CMake?

One simple way to list all subdirectories added in CMake is by using the get_property command with the DIRECTORY argument. Here's an example:

1
2

get_property(subdirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY SUBDIRECTORIES)
message("Subdirectories: ${subdirs}")

This will list all subdirectories added in the current CMake source directory. You can adjust the ${CMAKE_CURRENT_SOURCE_DIR} variable to specify a different directory if needed.
