On compiling optimization

[TXSF]

I would like to ask how to add optimization options (-O3 for example) when compiling, should I make changes to the Makefile?

Hello,

If you compile with cmake --build ./build, you can see the compilation flags when adding the --verbose option. Depending on the compiler and on the build type, the compiler options are mostly defined in https://github.com/xcompact3d/Incompact3d/tree/master/cmake/compilers

Cheers,

Thank you for your response! I have successfully changed the compilation flags by editing the files in /cmake/compilers. Besides, I found that the project should be rebuilt before compiling with the new options.
