In CMake, you can print variables using the message() function. This function is used to display messages or variable values during the CMake configuration process. To print a variable, you can simply pass the variable name to the message() function as an argument. For example, if you have a variable named MY_VAR, you can print its value like this:
1
|
message(STATUS "The value of MY_VAR is: ${MY_VAR}")
|
This will display the value of the variable MY_VAR during the CMake configuration process. Additionally, you can use different log levels such as STATUS, WARNING, or FATAL to control how the message is displayed. This can be helpful for debugging or providing information about the build process.
How to print out the value of a variable in CMake?
To print out the value of a variable in CMake, you can use the message command. Here is an example of how to print out the value of a variable named MY_VARIABLE:
1
|
message(STATUS "The value of MY_VARIABLE is: ${MY_VARIABLE}")
|
You can place this line of code anywhere in your CMake script to print out the value of the variable MY_VARIABLE to the console when the script is run.
How to display the contents of a variable in CMake?
To display the contents of a variable in CMake, you can use the message command. Here is an example of how to display the contents of a variable named MY_VARIABLE:
1
|
message("The value of MY_VARIABLE is: ${MY_VARIABLE}")
|
This will output the value of MY_VARIABLE to the console when the CMake script is executed. Alternatively, you can use the status command to also output the information to the console with additional information about where the message is coming from:
1
|
status("The value of MY_VARIABLE is: ${MY_VARIABLE}")
|
Both message and status commands are useful for debugging and verifying the values of variables in CMake scripts.
What is the best way to display the contents of a variable in CMake?
The best way to display the contents of a variable in CMake is to use the message() command. This command displays a message in the CMake console and can be used to display the contents of a variable.
For example, to display the contents of a variable named my_variable, you can use the following code:
1
|
message("Value of my_variable: ${my_variable}")
|
This will print the value of the variable my_variable to the CMake console when the CMake script is run.
How to display the value of a variable in CMake?
To display the value of a variable in CMake, you can use the message() command. Here is an example:
1 2 |
set(my_variable "Hello, World!") message("The value of my_variable is: ${my_variable}") |
When you run this CMake script, it will display the message "The value of my_variable is: Hello, World!" on the terminal. This allows you to see the value of the variable during the CMake configuration process.
What is the command line output for printing a variable in CMake?
To print a variable in CMake, you can use the message() command. Here is an example of how you can print a variable named "MY_VARIABLE":
1
|
message("The value of MY_VARIABLE is: ${MY_VARIABLE}")
|
When you run CMake with this command, it will output the value of the variable MY_VARIABLE.
