To get the target install location from CMake, you can use the CMAKE_INSTALL_PREFIX variable. This variable represents the base directory where targets will be installed. By using this variable in combination with the DESTINATION keyword in the INSTALL command, you can specify the installation directory for a specific target in your project. This allows you to define the exact location where each target should be installed during the build process.

How to print the target installation directory in a CMake project build log?
To print the target installation directory in a CMake project build log, you can add a custom command or script to output the installation directory at the end of the build process.
Here's an example of how you can achieve this in your CMakeLists.txt file:
1 2 3 4 5 6 7 8 9 |
# Define the target installation directory set(INSTALL_DIR ${CMAKE_INSTALL_PREFIX}/your_target_directory) # Add a custom command to print the installation directory add_custom_command( TARGET your_target_name POST_BUILD COMMAND ${CMAKE_COMMAND} -E echo "Installation directory: ${INSTALL_DIR}" ) |
Replace your_target_directory with the name of the directory where you want to install your target files, and your_target_name with the name of your target in the project.
After adding this to your CMakeLists.txt file, when you build your project, the build log should display the installation directory at the end of the build process.
What is the best way to determine the target install location in a CMake project configuration file?
One common approach to determine the target install location in a CMake project configuration file is to use the CMAKE_INSTALL_PREFIX variable. This variable specifies the root directory where files will be installed during the installation phase of the build process. By default, this variable is set to /usr/local, but it can be customized by the user.
Another way to determine the target install location is to explicitly specify the install location for each target in the project using the INSTALL command. This command allows you to specify the target, the destination directory, and any additional optional parameters for the installation. This approach gives you more control over where each target is installed.
Overall, the best way to determine the target install location in a CMake project configuration file depends on your specific project requirements and preferences. Consider using a combination of methods to achieve the desired installation behavior for your project.
What is the script to display the target install location in CMake?
To display the target install location in CMake, you can use the following script:
1
|
message("Install location: ${CMAKE_INSTALL_PREFIX}")
|
This will output the value of the CMAKE_INSTALL_PREFIX variable, which specifies the location where targets will be installed when the make install command is run.
