source: code/trunk/cmake/CompilerConfigMSVC.cmake @ 8707

Last change on this file since 8707 was 8368, checked in by rgrieder, 14 years ago

Added CMake configuration type "RelForDevs", which replaces "RelWithDebInfo". That latter is now equivalent to "Release", but with symbols.
Also, I removed debug symbol generation for Release and MinSizeRel when compiling with MSVC.

The new configuration should be used as standard Release mode when developing. The other three release configurations are for actual installed binaries (and behave again as the name suggests).
