# OPTIMIZATION_FLAGS <inout-variable>
# EXE_LINKER_FLAGS <inout-variable>
# INCLUDE_DIRS <inout-variable>

#
# Input:
# BOARD : flags depend on board/posix config
#
# Input/Output: (appends to existing variable)
# C_FLAGS : c compile flags variable
# CXX_FLAGS : c++ compile flags variable
# OPTIMIZATION_FLAGS : optimization compile flags variable
# EXE_LINKER_FLAGS : executable linker flags variable
# INCLUDE_DIRS : include directories
# LINK_DIRS : link directories
# DEFINITIONS : definitions
#
# Note that EXE_LINKER_FLAGS is not suitable for adding libraries because
# these flags are added before any of the object files and static libraries.
# Add libraries in src/firmware/posix/CMakeLists.txt.

# Example:
