# Rather than generating lists of headers to match CMake, the Bazel build
|
|
# opts to have a static header that transitively include two known headers.
|
|
# By default, empty header files are included, and users/platforms are expected
|
|
# to specify an appropriate `cc_library` to replace them.
|
|
#
|
|
# You tell bazel which `cc_library` provides the respective headers by
|
|
# configuring these `label_flag`s:
|
|
#
|
|
# # Specify the library that provides "pico_config_extra_headers.h"
|
|
# --@pico-sdk//bazel/config:PICO_CONFIG_EXTRA_HEADER=//my_proj:my_custom_headers
|

#
|

# # Specify the library that provides "pico_config_platform_headers.h"
