How do I include a semicolon in a cmake command?

To include a semicolon in a CMake command, you can simply enclose the command with double quotes. For example:

1
execute_process(COMMAND "echo hello; world")


In this example, the semicolon is included within the double quotes, which allows CMake to treat it as part of the command rather than as a delimiter.


How can I display a semicolon in the output of a cmake command?

To display a semicolon in the output of a cmake command, you can use the cmake command message to print the desired output to the terminal. When using message, you can use the ESC_SEMICOLON escape sequence (\;) to display a semicolon in the output.


For example, you can use the following command to display a semicolon in the cmake output:

1
message("This is a semicolon: \\;")


When you run this cmake command, it will output: "This is a semicolon: ;" to the terminal.


What is the workaround for printing a semicolon in cmake?

To print a semicolon in CMake, you can use the message() command with the OUTPUT_STRIP_TRAILING_WHITESPACE argument. Here's an example:

1
message("Printing a semicolon: \;")


This will output a semicolon to the console when the CMake script is executed. By escaping the semicolon with a backslash (;), you can prevent it from being interpreted as a delimiter in CMake.


How to prevent cmake from interpreting a semicolon as a delimiter in the output?

To prevent CMake from interpreting a semicolon as a delimiter in the output, you can use the OUTPUT_STRIP_TRAILING_WHITESPACE argument to the OUTPUT argument in the execute_process command. This argument trims any trailing whitespace from the output, which includes any semicolons.


For example, instead of using:

1
2
3
4
execute_process(
    COMMAND my_command
    OUTPUT_VARIABLE output
)


You can use:

1
2
3
4
5
execute_process(
    COMMAND my_command
    OUTPUT_VARIABLE output
    OUTPUT_STRIP_TRAILING_WHITESPACE
)


This will ensure that any semicolons in the output are treated as part of the output string rather than as delimiters.
