CMake provides several ways to turn off or change the optimization setting for a particular function:
set_property
function can be used to set the COMPILE_OPTIONS
property for a particular target or source file. For example, to turn off optimization for a specific source file, you can use the following command:set_property(SOURCE <source_file> PROPERTY COMPILE_OPTIONS "-O0")
This will set the -O0
option for the specified source file.
target_compile_options
function can be used to set compile options for a particular target. For example, to turn off optimization for a specific target, you can use the following command:target_compile_options(<target_name> PRIVATE "-O0")
This will set the -O0
option for the specified target.
cmake_minimum_required
function to set the minimum CMake version required for your project. By setting the minimum required version to a lower value, you can disable certain optimizations that are turned on by default in newer versions. For example, to disable -O2
optimization, you can use:cmake_minimum_required(VERSION 3.0)
This will set the minimum required CMake version to 3.0, which does not enable the -O2
optimization by default.
