How to Print Working_directory In Cmake?

3 minutes read

To print the working directory in CMake, you can use the following command:

1

message(STATUS "Working directory: ${CMAKE_CURRENT_SOURCE_DIR}")


This command will print the current source directory in CMake. CMake provides several variables that give you information about the current build environment, including the source directory. Using the message command with the STATUS keyword allows you to print this information to the console during the build process.


How do I access the working directory information in CMake for debugging purposes?

You can access the working directory information in CMake by using the following command in your CMakeLists.txt file:

1

message(STATUS "Current working directory: ${CMAKE_CURRENT_SOURCE_DIR}")


This will print out the current working directory path to the console when you run CMake. Additionally, you can also use the get_cmake_property command to access the source directory and binary directory paths:

1
2
3
4

get_cmake_property(_variableNames VARIABLES)
foreach (_variableName ${_variableNames})
    message(STATUS "${_variableName}=${${_variableName}}")
endforeach()


This will print out all the CMake variables and their values, including the source and binary directory paths. This information can be helpful for debugging purposes when working with CMake.


What is the command to output the working directory path in CMake?

The command to output the working directory path in CMake is:

1

message(STATUS "Current working directory: ${CMAKE_CURRENT_SOURCE_DIR}")



How do I display the working directory path in CMake?

To display the working directory path in CMake, you can use the message command to print out the value of the CMAKE_CURRENT_SOURCE_DIR or CMAKE_CURRENT_BINARY_DIR variables. These variables represent the source directory and binary directory of the current project, respectively.


Here's an example of how you can display the working directory path in CMake:

1
2

message("Source directory: ${CMAKE_CURRENT_SOURCE_DIR}")
message("Binary directory: ${CMAKE_CURRENT_BINARY_DIR}")


When you run CMake on your project, these messages will print out the full paths of the source and binary directories.


What is the correct format for printing the working directory in CMake?

To print the working directory in CMake, you can use the following command:

1

message(STATUS "Current working directory: ${CMAKE_CURRENT_SOURCE_DIR}")


This command will print the current working directory of the CMake script and provide you with the path to the directory where the CMake script is being executed.


How to ensure the accuracy of the working directory information printed in CMake?

To ensure the accuracy of the working directory information printed in CMake, you can follow these best practices:

  1. Use the message command to print the working directory information in CMake. This command will display the specified message in the CMake output and can be helpful for debugging purposes.
  2. Make sure to use the built-in CMake variables such as ${CMAKE_CURRENT_SOURCE_DIR} or ${CMAKE_CURRENT_BINARY_DIR} to accurately determine the current working directory.
  3. Avoid hardcoding paths in your CMake scripts and instead use relative paths or variables to dynamically determine the working directory at runtime.
  4. Verify the working directory information by running CMake in verbose mode (cmake --debug-output) to see detailed output including the paths and directories being used.
  5. Test your CMake scripts on different platforms and environments to ensure that the working directory information is consistent and accurate across all systems.


By following these best practices, you can ensure that the working directory information printed in CMake is accurate and reliable for your project.


How to easily find and print the working directory in CMake?

In CMake, you can easily find and print the working directory using the following commands:

  1. Use the get_filename_component command to get the full path of the current CMake source directory:
1
2

get_filename_component(CMAKE_SOURCE_DIR_FULL_PATH "${CMAKE_SOURCE_DIR}" ABSOLUTE)
message("CMake source directory: ${CMAKE_SOURCE_DIR_FULL_PATH}")


  1. Use the get_filename_component command to get the full path of the current build directory:
1
2

get_filename_component(CMAKE_BINARY_DIR_FULL_PATH "${CMAKE_BINARY_DIR}" ABSOLUTE)
message("CMake binary directory: ${CMAKE_BINARY_DIR_FULL_PATH}")


These commands will retrieve the full path of both the source directory and the build directory in CMake and print them to the console.
