To force CMake to put options after the filename, you can use the -- separator. This basically tells CMake that any option mentioned after -- should be treated as a filename and not an option. This can be useful when you have filename options that start with a dash, which might otherwise confuse CMake. By using --, you can specify the filename option without any confusion with other command line options.

How to include custom cmake toolchain options after the filename?
To include custom CMake toolchain options after the filename, you can pass them as arguments when running the CMake command. For example:
1
|
cmake -DCMAKE_TOOLCHAIN_FILE=my_toolchain_file.cmake -DOPTION1=value1 -DOPTION2=value2 ..
|
In this command, my_toolchain_file.cmake is the custom toolchain file you want to include, and OPTION1 and OPTION2 are the custom options you want to set. Make sure to replace value1 and value2 with the desired values for the options.
You can add as many custom toolchain options as needed after the filename by continuing to use the -D flag followed by the option name and value.
How to reorder cmake options to come after the filename?
Unfortunately, CMake does not allow for reordering options to come after the filename. The order of options in a CMake command is important and must be followed as specified in the CMake documentation. However, you can still achieve flexibility by using variables or scripts to set the options before calling the CMake command.
What are the potential pitfalls of not putting cmake options after the filename?
- Incorrect interpretation: Without specifying cmake options after the filename, cmake may misinterpret the options as part of the filename, leading to errors or incorrect behavior. This may result in the build process being disrupted or producing unexpected results.
- Missed customization: By not specifying cmake options after the filename, you may miss out on important customization options that could optimize your build process or enable specific features in your project.
- Inconsistency: Not consistently specifying cmake options after the filename may lead to inconsistencies in how your project is built across different environments or systems. This can cause compatibility issues and make it difficult to maintain and debug your project.
- Limited control: Without putting cmake options after the filename, you may have limited control over how your project is built and configured. This can make it harder to troubleshoot issues or make changes to your build process in the future.
- Missed troubleshooting opportunities: When cmake options are not specified after the filename, it may be harder to troubleshoot build errors or conflicts that arise during the build process. This can make it more challenging to diagnose and resolve issues in your project.
