Introduce add_compile_options command. This command is similar to add_definitions, in that it affects the compile options of all targets which follow it. The implementation is similar to the implementation of the include_directories command, in that it is based on populating a COMPILE_OPTIONS directory property and using that to initialize the same property on targets. Unlike the include_directories command however, the add_compile_options command does not affect previously defined targets. That is, in the following code, foo will not be compiled with -Wall, but bar will be: add_library(foo ...) add_compile_options(-Wall) add_library(bar ...) 2013-06-04 12:30:24 +04:00			`cmake_minimum_required(VERSION 2.8)`
