Hello. I want to add some preprocessor flags to both my sources and other project components.

For make I create

Makefile.projbuild

with

Code: Select all

CPPFLAGS += -DMY_LOVELY_DEFINITION

How can I do that with CMake?

Ok, got it by myself

.

Solution: add

Code: Select all

target_compile_options(${COMPONENT_TARGET} PUBLIC -DYOUR_LOVELY_DEFINITIONS)

somwhere after

Code: Select all

register_component()

in your component's CMakeLists.txt.
Hope that it will help somebody!
P.S.: it is probably also a good idea to warp it into fuction like "project_compile_options" or "global_compile_options".
