To use wildcards in cmake install, you can use the INSTALL command followed by the DIRECTORY keyword to specify the directory containing files you want to install. You can use wildcards within the directory path or file names to match multiple files or directories.
For example, if you want to install all .txt files within a directory, you can use the following command:
1 2 3 4 |
install(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/data/ DESTINATION ${CMAKE_INSTALL_PREFIX}/data FILES_MATCHING PATTERN "*.txt" ) |
This will install all .txt files from the data directory in your source directory to the data directory in your install directory. Similarly, you can use wildcards to match specific file names or extensions to install multiple files at once.

How to enhance flexibility in file selection with wildcards in CMake install?
To enhance flexibility in file selection with wildcards in CMake install, you can use the DIRECTORY parameter in the install(DIRECTORY ...) command in CMake.
Here is an example of how you can use wildcards in the install(DIRECTORY ...) command:
1 2 3 4 |
install(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/path/to/files/ DESTINATION ${CMAKE_INSTALL_PREFIX}/path/to/install/ FILES_MATCHING PATTERN "*.txt" ) |
In this example, ${CMAKE_CURRENT_SOURCE_DIR}/path/to/files/ is the source directory containing the files you want to install, and ${CMAKE_INSTALL_PREFIX}/path/to/install/ is the destination directory where you want to install the files. The FILES_MATCHING PATTERN "*.txt" option specifies that only files with the .txt extension will be installed.
You can use wildcards such as * and ? to match multiple files or characters in the file names. This can provide flexibility in selecting files for installation based on specific patterns or criteria. You can also use regular expressions to define more complex file selection patterns.
By using the FILES_MATCHING PATTERN option in the install(DIRECTORY ...) command, you can enhance flexibility in file selection with wildcards in CMake install.
How to efficiently use wildcards for installing multiple files in CMake?
To efficiently use wildcards for installing multiple files in CMake, you can use the file(GLOB) command to generate a list of files that match a certain pattern and then use a loop or a list to install them. Here's an example of how you can do this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
# Specify a directory containing files to be installed set(FILES_TO_INSTALL "${CMAKE_CURRENT_SOURCE_DIR}/path/to/files/*.txt") # Use file(GLOB) to get a list of files matching the pattern file(GLOB FILES_MATCHING_PATTERN "${FILES_TO_INSTALL}") # Loop over the list and install each file foreach(file ${FILES_MATCHING_PATTERN}) # Get the file name without the path get_filename_component(file_name ${file} NAME) # Install each file to a specific directory install(FILES ${file} DESTINATION ${CMAKE_INSTALL_PREFIX}/destination/path/${file_name}) endforeach() |
In this example, the file(GLOB) command is used to generate a list of files matching the pattern *.txt in the specified directory. The list of files is then looped over, and each file is installed to a specific destination path using the install() command.
By using wildcards with file(GLOB) and a loop, you can efficiently install multiple files in CMake without having to specify each file individually.
What is the purpose of using wildcards in CMake install?
The purpose of using wildcards in CMake install is to simplify the installation process for files that match a certain pattern or criteria. This can be useful when you have a large number of files or directories that need to be installed, and you want to specify them using a more general pattern rather than listing each file individually. Wildcards allow you to match files based on their names or paths, making it easier to handle changes to the file structure or additions of new files without needing to constantly update the CMake install commands.
What is the impact on performance when using wildcards in CMake install?
Using wildcards in CMake install can have a negative impact on performance as it requires CMake to look through all files in a directory to find matching files. This can slow down the installation process, especially when dealing with large numbers of files. Additionally, using wildcards can make the installation less predictable as it may include unexpected files if the wildcard pattern is not precise enough. It is generally recommended to specify individual files or directories explicitly in the install commands in CMake to ensure better performance and predictability.
What is the impact of using wildcards on the directory structure in CMake install?
Using wildcards in the directory structure in CMake install can affect the behavior of the installation process. While wildcards can be an efficient way to refer to multiple files or directories without explicitly listing them, there are some potential impacts to be aware of:
- Unpredictable behavior: Using wildcards may lead to unpredictable behavior if the files or directories matching the wildcard pattern change over time. This can result in unintended files being installed or files being missed during the installation process.
- Limited control: Wildcards may not provide the level of control that is needed for specifying the exact files or directories to be installed. This can lead to inconsistent installation results, especially when dealing with complex directory structures.
- Difficulty in debugging: When issues arise during the installation process, it can be more challenging to debug and troubleshoot problems that are related to wildcard usage. Tracking down the source of the issue may require manually inspecting the directory structure to determine which files or directories are being affected.
- Dependency management: Wildcards may not handle dependencies between files or directories correctly, leading to potential issues with installation dependencies and conflicts. This can result in incomplete installations or conflicts with other components of the project.
Overall, while wildcards can be a convenient way to specify files or directories in the CMake install process, it is important to carefully consider the potential impacts and limitations that may arise from their usage. It is recommended to use wildcards judiciously and to test the installation process thoroughly to ensure that the desired files and directories are being installed correctly.
What is the significance of wildcard expansion in CMake install?
Wildcard expansion in CMake install is significant because it allows for the installation of files matching a certain pattern or criteria without having to explicitly list each file individually. This makes the installation process more efficient and reduces the risk of errors or omissions. Additionally, wildcard expansion can help streamline the installation of large numbers of files or files with complex naming conventions. Overall, wildcard expansion in CMake install simplifies the installation process and improves maintainability of the project.
