1、 -O参数：-O全称是Optimization（优化），用于设置编译器使用的优化级别。一般来说，编译器可支持0，1，2，3级优化等级，数字越大，优化级别越高。-O3为最高级。2、 -g参数：-g 全称是Debug (调试开关)，用于附加在编译的代码中的调试信息，此参数能够帮助在不同的运行环境中进行调试。3、-W...

export CFLAGS="-Wall" ``` By setting the CFLAGS variable in this way, developers can ensure that their code is compiled with the desired level of warnings enabled. Another common use case for the Linux Export CFLAGS command is to specify optimization flags. For example, developers can use th...

In addition to the general optimization of cflags, the flags can also be used to provide security features. For example, the security flag ‘with-stack-protector’ can be used to give the system additional protection against stack-based buffer overflows.Cflags provide a powerful tool ...
You could try the cache_variables or variables, but also changing those is risky, because the optimization flag is not the only one, so you might be dropping other necessary variables, so I would still recommend trying a pure CMake solution. Author maitrey commented Sep 13, 2022 • ...
