CMake: default build mode and compiler flags for optimisation #440

Closed GPMueller closed 6 years ago

GPMueller commented 6 years ago

If no mode is specified, it should default to release mode.

The core library should probably have it's own compiler flags and adequately use optimisation flags (note: also add nvcc flags)! Their absence might well be contributing to #385.

It appears that the optimization flags can make a significant difference in startup time of the code, as well as for example setting spin configurations - it seems this may be responsible for or contributing to #144.

Fixed the placement of the default build type with dd01b55cb1c0e2af488f2199c70e3a4a6f8307fb. This fixes the regular compiler flags, as well as the nvcc flags.

This also significantly improves the situation of #144.
