To clear all defines from CMake, you can use the following command:
1
|
cmake -U <DEFINE>
|
This command will unset the specified define, effectively clearing it from the CMake cache. You can use this command multiple times to clear multiple defines.

What is the best practice to clear all defines for a fresh start in CMake project?
The best practice to clear all defines for a fresh start in a CMake project is to remove the CMakeCache.txt file in the project's build directory. This file stores all the cached variables and settings used during the configuration process, including defines.
To clear all defines and start fresh, you can follow these steps:
- Delete the CMakeCache.txt file in the build directory of your project. This will remove all cached variables and settings.
- Delete the contents of the build directory (except for any necessary files like source files or CMakeLists.txt).
- Run CMake again to configure the project from scratch. This will generate a new CMakeCache.txt file with default settings.
By following these steps, you can clear all defines and other cached settings in a CMake project and start fresh with a clean configuration.
How to delete all defines from CMakeLists.txt file?
To delete all the defines from a CMakeLists.txt file, you can simply remove or comment out the lines that set the defines. Defines are typically set using the "add_definitions" command in CMake. Here is an example of how you can remove all defines from a CMakeLists.txt file:
- Open the CMakeLists.txt file in a text editor.
- Look for any lines that use the "add_definitions" command to set defines. These lines will look something like this:
1
|
add_definitions(-DDEFINE1 -DDEFINE2)
|
- Comment out or delete these lines to remove the defines. For example:
1
|
#add_definitions(-DDEFINE1 -DDEFINE2)
|
- Save the file and re-run CMake to regenerate the build system without the defines.
By following these steps, you can easily delete all defines from a CMakeLists.txt file.
What is the proper way to clear all set options and flags in CMakeLists.txt?
To clear all set options and flags in a CMakeLists.txt file, you can unset any variables that have been previously set. Here is an example of how you can clear all set options and flags in CMakeLists.txt:
1 2 3 4 5 |
# Clear all set options and flags unset(OPTION1 CACHE) unset(OPTION2 CACHE) unset(FLAG1 CACHE) unset(FLAG2 CACHE) |
By using the unset command with the CACHE option, you can remove any previously set options or flags in the CMakeLists.txt file. This will effectively clear all set options and flags, allowing you to start fresh with setting new options and flags for your project.
What is the correct way to delete all cache entries from a CMake project?
To delete all cache entries from a CMake project, you can run the following command in the terminal:
1
|
cmake --build . --target clean
|
This command will clean all the cache entries in the project and you can start fresh with a clean slate.
