4 min readTo convert configure options for use with cmake, you need to first identify the options that you want to convert. Then, you should create a CMakeLists.txt file in your project directory and use the "option()" command to define CMake options that correspond to the configure options. Next, set the default values for these options using the "set()" command.

3 min readTo append a semicolon to a CMake string, you can simply concatenate the semicolon with the existing string using the string concatenation operator (+). For example, if you have a CMake variable named MY_STRING and you want to append a semicolon to it, you can do so like this: set(MY_STRING "${MY_STRING};") This will add a semicolon to the end of the existing string in the MY_STRING variable. You can then use this updated string in your CMake scripts as needed.

3 min readTo call a CMake method from a shell script, you can use the cmake command followed by the arguments required to invoke the specific method. For example, if you want to build a CMake project using a specific build type, you can call the cmake command with the -DCMAKE_BUILD_TYPE flag set to the desired build type (e.g. Debug or Release). Additionally, you can also pass other flags and options to customize the build process according to your requirements.
-
5 min readTo use find_package in CMake, you simply need to include the find_package command in your CMakeLists.txt file and specify the package you want to locate. CMake will then search for the specified package and generate the necessary variables to link with the package in your project. Make sure to provide the correct package name and version to ensure CMake can locate the package successfully.

6 min readRegular expressions can be used in CMake by utilizing the MATCHES keyword. By specifying MATCHES and providing a regular expression pattern, CMake can be used to match and filter strings. Regular expressions enable developers to perform pattern matching and string manipulation tasks in CMake scripts, allowing for more sophisticated and flexible processing of strings and variables.

6 min readIn CMake, pre-building a library involves specifying the source files, compiling them, and linking them into a library target. To pre-build a library in CMake, you need to create a CMakeLists.txt file in the directory containing the library source files.In the CMakeLists.txt file, you should first define the library target using the "add_library" command, specifying the name of the library and its source files.
-
6 min readTo add a resource in CMake on Windows, you can use the add_executable and add_custom_command commands to include the resource file in your project. First, create a resource file (typically with a .rc extension) that contains the icons, bitmaps, or other resources you want to use. Next, add the resource file to your CMake project using the add_executable command and specify the resource file as a source file.
-
5 min readTo run compound script statements from CMake, you can use the execute_process command within your CMakeLists.txt file. This command allows you to invoke commands and scripts directly from CMake.To run compound script statements, you can specify the full command as a single string in the COMMAND option of the execute_process command. This allows you to run multiple commands or scripts in sequence by separating them with && or ;.
-
6 min readTo use the debug macro with cmake, you can define a CMake variable for enabling debug mode, such as setting DEBUG_MODE to ON. Then, you can use an IF statement to check if the debug mode is enabled and add the necessary compiler flags or options for debugging, such as -g for gcc. This allows you to easily toggle between debug and release builds by changing the value of the DEBUG_MODE variable.
-
6 min readIn CMake, you can remove a specific compiler warning by passing the appropriate flag or option to the compiler during the configuration of your project. To do this, you can use the add_compile_options() or target_compile_options() functions in your CMakeLists.txt file.For example, if you want to remove a specific warning such as -Wall (which enables all warnings) you can use add_compile_options(-Wall -Wno-specific-warning) to enable all warnings but disable a specific one.

5 min readIn PowerShell, you can skip downloading a file if it already exists by using the Test-Path cmdlet to check if the file already exists in the specified directory. If the file exists, you can use an if statement to skip the download process and display a message indicating that the file already exists. If the file does not exist, you can proceed with downloading the file as usual.

3 min readTo move-up or move-down a Windows language using PowerShell, you can use the following command: Set-WinUILanguageOverride This command allows you to change the display language used in Windows. By specifying the language code as a parameter with this command, you can switch to a different language or move it up or down in the language list. This can be useful for managing multiple languages on a Windows system or changing the default display language.
