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 ...)

cmTarget: Don't update IMPORTED target compilation properties The include_directories() and add_compile_options() commands should not append to the corresponding target property for IMPORTED targets. This is already the case for add_definitions().
