To print all compile options in CMake, you can use the following command:
1
|
cmake --help-variable CMAKE_CXX_FLAGS
|
This command will display all the compile options related to C++ in CMake. You can replace CMAKE_CXX_FLAGS with other variables like CMAKE_C_FLAGS or any other target-specific variable to see the compile options for that specific target.

How to view cmake compile options?
To view the compile options used by CMake, you can run CMake with the -LA or --trace flag. This will print out a list of the cache entries along with their current values.
For example, you can run the following command in the terminal:
1
|
cmake -LA <path_to_source_code>
|
This will show you all the compile options that were set in the CMakeLists.txt file or through the command line when configuring the project.
How to find out what compile options are used in cmake?
To find out what compile options are used in a CMake build, you can use the following commands:
- Generate the build system: Run the cmake command in the root directory of your project to generate the build system. This will create the necessary build files such as Makefile or Visual Studio project files.
- View the compiler flags: Once the build system is generated, you can view the compiler flags that are being used by looking at the generated Makefile or project files. Look for the CMAKE_CXX_FLAGS or CMAKE_C_FLAGS variables in the generated files to see the compiler flags being used.
- Use the ccmake tool: You can also use the ccmake tool to interactively view and modify the CMake configuration settings. Run the ccmake command in the build directory to bring up the CMake configuration interface, where you can see all the CMake variables, including the compile options.
- Use the --trace-expand option: You can also use the --trace-expand CMake option to print out the expanded values of all CMake variables, including the compile options. Run cmake --trace-expand . in the build directory to see the expanded values.
By following these steps, you can easily find out what compile options are being used in a CMake build.
How to demonstrate all compile options in cmake configuration.
In order to demonstrate all compile options in a CMake configuration, you can use the following commands:
- To view all available CMake options for a project, use the command:
1
|
cmake path_to_project -LH
|
- To display all available build configurations for a project, use the command:
1
|
cmake path_to_project -LAH
|
- To display detailed information about the CMake cache, use the command:
1
|
ccmake path_to_project
|
This will open a GUI interface where you can view and modify all CMake options.
- To generate a list of all CMake variables and their values for a project, use the command:
1
|
cmake path_to_project -LA
|
By using these commands, you can easily view and modify all compile options in a CMake configuration.
How to find compile options in cmake?
To find the compile options in CMake, you can use the following command in your terminal:
1
|
cmake --help-variable CMAKE_CXX_FLAGS
|
This command will display the compiler options that are commonly used with CMake. You can also substitute CMAKE_CXX_FLAGS with other variables such as CMAKE_C_FLAGS or CMAKE_CXX_COMPILER to see specific compile options for C or C++ respectively.
Additionally, you can check the CMakeLists.txt file in your project to see if any specific compiler options are set using the add_compile_options command. These options will be listed in the CMake file.
How to inspect compile options in cmake?
To inspect compile options in CMake, you can use the CMake command get_property along with the COMPILE_OPTIONS property. This command retrieves a list of compilation options for a specific target or directory.
Here is an example of how you can inspect compile options in CMake:
- Open your CMakeLists.txt file in a text editor.
- Use the following command to retrieve the compile options for a specific target, for example "my_target": get_property(COMPILE_OPTIONS_TARGETS TARGET my_target PROPERTY COMPILE_OPTIONS) message("Compile options for my_target: ${COMPILE_OPTIONS_TARGETS}")
- Use the following command to retrieve the compile options for the current directory: get_property(COMPILE_OPTIONS DIRECTORY PROPERTY COMPILE_OPTIONS) message("Compile options for current directory: ${COMPILE_OPTIONS}")
- Run CMake in the terminal to see the output of the compile options for the specified target or directory.
By using these commands, you can inspect and view the compilation options set for your CMake project.
