To use the export custom target with CMake, you can define a custom target in your CMakeLists.txt file using the add_custom_target() command. Within this custom target, you can specify commands to be executed when the target is built.
To export this custom target, you can use the EXPORT() command along with the INSTALL() command. The EXPORT() command creates an export set that contains the custom target, while the INSTALL() command installs this export set so it can be used by other CMake projects.
Additionally, you can use the install(EXPORT) command in another CMakeLists.txt file to import the custom target from the export set and use it in that project.
Overall, using export custom targets with CMake allows you to define and share custom build commands or actions in your project.
What is the difference between custom target and regular target in CMake?
In CMake, a custom target is a target that is defined by the user with custom commands and dependencies. This allows users to define custom build rules that are not provided by CMake's built-in target types.
On the other hand, a regular target is a target that is defined by CMake with standard build rules and properties. Regular targets can include executables, libraries, or custom commands defined by CMake.
In summary, the main difference between custom targets and regular targets in CMake is that custom targets are user-defined with custom build rules, while regular targets are predefined by CMake with standard build rules and properties.
What is the difference between custom target and custom command in CMake?
In CMake, a custom target is a target that does not create an output file or build artifacts. It is used to group other targets or provide additional actions as part of the build process. Custom targets can be used to run scripts, execute commands, or perform other actions during the build process.
On the other hand, a custom command is used to define a specific command that should be executed as part of the build process. This command can be used to generate source files, build additional artifacts, or perform other tasks required for the build. Custom commands are typically associated with one or more targets and are executed during the build process to generate necessary files or perform required actions.
In summary, a custom target is used to group other targets or provide additional actions in the build process, while a custom command defines specific commands to be executed as part of the build process.
How to specify dependencies for a custom target in CMake?
To specify dependencies for a custom target in CMake, you can use the add_dependencies() function. Here is an example of how to specify dependencies for a custom target:
1 2 3 4 5 6 7 8 |
# Add your custom target add_custom_target(my_custom_target COMMAND <command_to_run> DEPENDS dependency1 dependency2 ) # Specify additional dependencies for the custom target add_dependencies(my_custom_target additional_dependency1 additional_dependency2) |
In this example, <command_to_run> is the command you want to run for the custom target, and dependency1 and dependency2 are the dependencies required for the custom target. The add_dependencies() function is then used to specify additional dependencies for the custom target.
Make sure to replace <command_to_run>, dependency1, dependency2, additional_dependency1, and additional_dependency2 with the actual commands and dependencies in your CMake project.
