How to Exclude A Sub Directory From Cmake File?

To exclude a subdirectory from a CMake file, you can use the EXCLUDE_FROM_ALL keyword when adding the subdirectory in your CMakeLists.txt file. This keyword will prevent the subdirectory from being included in the build process when you run make. This is useful when you have a subdirectory that you do not want to include in the build for some reason, such as containing test files or other non-essential components. By using the EXCLUDE_FROM_ALL keyword, you can control which directories are included in the build process and keep your build streamlined and efficient.

How to avoid including certain directories in cmake build system?

To avoid including certain directories in the CMake build system, you can use the EXCLUDE_FROM_ALL option in the add_subdirectory() function.

For example, if you want to exclude a directory named excluded_dir, you can modify your CMakeLists.txt file like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

# Include all directories except 'excluded_dir'
add_subdirectory(dir1)
add_subdirectory(dir2)
add_subdirectory(dir3)

# Exclude 'excluded_dir' from the build system
if(NOT ${CMAKE_CURRENT_SOURCE_DIR} STREQUAL ${CMAKE_CURRENT_BINARY_DIR})
    if(NOT EXISTS ${CMAKE_CURRENT_BINARY_DIR}/excluded_dir)
        add_subdirectory(excluded_dir EXCLUDE_FROM_ALL)
    endif()
endif()

This way, the excluded_dir directory will not be included in the build system, but the other directories will still be built.

What is the correct command to skip a sub directory in cmake build?

To skip a subdirectory in the cmake build, you can use the EXCLUDE_FROM_ALL option in the add_subdirectory command. This option specifies that the target should not be included in the default target list when the ALL target is built.

Here is the correct command to skip a subdirectory in cmake build:

1

add_subdirectory(subdirectory_name EXCLUDE_FROM_ALL)

Replace subdirectory_name with the name of the subdirectory that you want to skip in the cmake build.

How to ignore a sub directory in cmake configuration?

To ignore a subdirectory in CMake configuration, you can use the CMakeLists.txt file inside the parent directory to exclude the subdirectory. You can do this by adding a condition to check if the subdirectory should be included or not.

For example, let's say you have a parent directory with two subdirectories named subdir1 and subdir2, and you want to ignore subdir2. You can modify the CMakeLists.txt in the parent directory as follows:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

# CMakeLists.txt in parent directory

# List all the subdirectories
add_subdirectory(subdir1)

# Check if subdir2 should be included or not
option(INCLUDE_SUBDIR2 "Include subdir2" ON)
if(INCLUDE_SUBDIR2)
    add_subdirectory(subdir2)
endif()

By setting the INCLUDE_SUBDIR2 option to OFF, you can ignore subdir2 during the CMake configuration. To do this, run the cmake command with the -D option to set the value:

1

cmake -DINCLUDE_SUBDIR2=OFF path_to_parent_directory

This way, you can control whether a subdirectory should be included or ignored in the CMake configuration.

What is the command to exclude a sub directory in cmake script?

To exclude a sub directory in a CMake script, you can use the EXCLUDE_FROM_ALL option with the add_subdirectory command. Here is an example:

1

add_subdirectory(subdirectory_name EXCLUDE_FROM_ALL)

This command will exclude the specified subdirectory from the build process when building the main project.

What is the correct way to exclude a folder from cmake build process?

To exclude a folder from the CMake build process, you can use the CMakeLists.txt file in the root directory of your project.

To exclude a folder from being built, you can use the add_subdirectory() command with the EXCLUDE_FROM_ALL option. This will prevent the specified folder from being built when you run the make command.

For example, if you want to exclude a folder named folder_to_exclude, you can add the following line in your CMakeLists.txt file:

1

add_subdirectory(folder_to_exclude EXCLUDE_FROM_ALL)

This will exclude the folder_to_exclude from the build process. Make sure to rerun the CMake configuration after making this change.
