To print a ";" symbol using CMake command, you can simply use the message command along with the desired string containing the ";" symbol. For example, you can write:
1
|
message("Printing a semi colon: ;")
|
This command will output on the console:
1
|
Printing a semi colon: ;
|
How to handle semicolons in CMake options?
In CMake, semicolons are used to separate multiple values in a list. When defining options in CMake, it is important to properly handle semicolons to avoid unexpected behavior.
Here are some tips on how to handle semicolons in CMake options:
- Use double quotes: When setting an option value that contains semicolons, enclose the value in double quotes. This will ensure that the semicolons are treated as part of the value and not as separators.

|
set(MY_OPTION "value1;value2" CACHE STRING "Description")
|
- Use list syntax: If you need to pass a list of values to an option, you can use the list syntax in CMake. This involves using the ; character to separate the values, without enclosing the entire list in double quotes.

|
set(MY_OPTION value1;value2 CACHE STRING "Description")
|
- Use CMake built-in functions: If you need to manipulate a string that contains semicolons, you can use CMake's built-in string functions to split or join the values as needed.

|
string(REPLACE ";" "|" MY_OPTION "value1;value2")
|
By following these tips, you can handle semicolons in CMake options effectively and avoid errors in your CMake configuration.
How to escape a semicolon in CMake?
To escape a semicolon in CMake, you can use the backslash () character before the semicolon. This will tell CMake to treat the semicolon as a regular character and not as a delimiter for separating arguments.
For example, if you want to pass a string that contains a semicolon as an argument to a CMake command, you can escape the semicolon like this:
1
|
set(my_string "Hello\; World")
|
In this example, the semicolon in the string "Hello; World" is escaped with a backslash.
Alternatively, you can also use double quotes to enclose the string, which will prevent the semicolon from being treated as a delimiter:
1
|
set(my_string "Hello; World")
|
Either of these methods will allow you to include a semicolon in a string in CMake without it being interpreted as a separator.
How to interpret semicolons in CMake configuration files?
Semicolons in CMake configuration files are used as list separators. They are mainly used to separate items within a list. For example, when defining include directories or linking libraries, you would separate each directory or library with a semicolon.
It is important to note that semicolons are not used as statement terminators in CMake configuration files, unlike in some other programming languages. Instead, each line in a CMake configuration file is a separate command or setting, and semicolons are used only within a specific command or setting to separate individual items.
When interpreting semicolons in CMake configuration files, it is important to keep in mind their usage as list separators and ensure that they are used correctly within the context of the specific command or setting being used.
How to encode a semicolon in CMake source files?
In CMake source files, a semicolon can be encoded by using the escape character \;
. This tells CMake to treat the semicolon as a literal character rather than as a delimiter.
For example, you can encode a semicolon in a CMake source file like this:
1
|
set(my_variable "value\;with\;semicolon")
|
This will set the variable my_variable
to the value "value;with;semicolon".
What is the role of semicolons in CMake code organization?
In CMake code organization, semicolons are used to separate different items within lists and strings.
Specifically, semicolons are commonly used to separate different paths or options when setting variables, specifying file paths, or passing arguments to various CMake functions.
For example, when adding source files to a target, the list of source files should be separated by semicolons:
1 2 3 4 5 |
set(SOURCES source_file1.cpp source_file2.cpp source_file3.cpp ) |
In addition, semicolons can also be used to concatenate multiple commands on a single line in CMake code.
Overall, semicolons play a crucial role in defining the structure of CMake scripts and correctly organizing the various components within them.
What is the workaround for printing a semicolon in CMake?
The workaround for printing a semicolon in CMake is to use the MESSAGE
command with the HEX
argument. This will allow you to print the hexadecimal value of the semicolon character, which can be converted back to a semicolon when needed. Here is an example:
1 2 |
# Print the hexadecimal value of the semicolon character MESSAGE(HEX "\;") |
This will output the hexadecimal value of the semicolon character, which you can then convert back to a semicolon in your code.
