feat(build): propagate compiler flags from files to toolchain.cmake
This change improves build consistency across external projects integrated through CMake by ensuring that compiler flags defined in configuration files are passed correctly to the toolchain. It covers the majority of use cases, as external projects are typically also CMake-based. For projects that use a custom build system, users will still need to specify the required flags manually.

# This function adds flags to the appropriate toolchain response files (cflags, cxxflags,

# asmflags, or ldflags) in the IDF_TOOLCHAIN_BUILD_DIR directory. Duplicate flags
|
||||
# are automatically removed before adding new ones.
|

#
|

# @param[in, optional] COMPILE_OPTIONS (multivalue) flags to add to C, C++, and ASM
|
||||
# compilation. Applied to cflags, cxxflags, and asmflags files.
|
||||
# @param[in, optional] C_COMPILE_OPTIONS (multivalue) flags to add to C compilation only.
|
||||
# Applied to cflags file.
|
||||
# @param[in, optional] CXX_COMPILE_OPTIONS (multivalue) flags to add to C++ compilation only.
|
||||
# Applied to cxxflags file.
|
||||
# @param[in, optional] ASM_COMPILE_OPTIONS (multivalue) flags to add to ASM compilation only.
|
||||
# Applied to asmflags file.
|
||||
# @param[in, optional] LINK_OPTIONS (multivalue) flags to add to linking.

# Applied to ldflags file.
|

#
|

# @note Multiple keyword arguments can be specified in a single call.

# @note Flags are deduplicated - if a flag already exists in the file, it will be

# removed before adding the new one to ensure no duplicates.

#
|

# Example:
|

# idf_toolchain_add_flags(COMPILE_OPTIONS "-Wall" "-Wextra")

# idf_toolchain_add_flags(C_COMPILE_OPTIONS "-std=c99" LINK_OPTIONS "-Wl,--gc-sections")
