How to Append Semicolon (;) to Cmake String?

2 minutes read

To append a semicolon (;) to a CMake string, you can simply concatenate the semicolon to the existing string using the ${} syntax. For example, if you have a variable named MY_STRING and you want to add a semicolon at the end, you can do so by using the following command:


set(MY_STRING "${MY_STRING};")


How to insert a semicolon at a specific position in a cmake string?

To insert a semicolon at a specific position in a CMake string, you can use the string manipulation functions available in CMake. One way to do this is by using the STRING command and the string subcommand to insert a semicolon at a specific position in the string.


Here is an example of how you can insert a semicolon at position 5 in a CMake string:

1
2
3
4
5
6

set(myString "Hello World")

# Insert a semicolon at position 5
string(INSERT myString 5 ";")

message(STATUS "Modified string: ${myString}")


This will output:

1

Modified string: Hello; World


You can adjust the position parameter in the string(INSERT ...) command to insert the semicolon at a different position in the string.


How to replace a comma with a semicolon in a cmake string?

To replace a comma with a semicolon in a CMake string, you can use the string(REPLACE) command. Here is an example of how you can do it:

1
2
3

set(original_string "this,is,a,test")
string(REPLACE "," ";" new_string ${original_string})
message(${new_string})


In this example, the original string is "this,is,a,test" and we want to replace the commas with semicolons. The string(REPLACE) command does this for us and stores the result in the new_string variable. Finally, we use the message() command to print the new string to the console.


You can adjust this example to replace commas with semicolons in any CMake string by changing the value of the original_string variable.


What is the simplest way to append a semicolon to a cmake string?

1
2

set(my_string "${my_string};")


In this example, the semicolon is appended to the my_string variable.
