CMake target_link_libraries order problems

Postby pinock » Wed Dec 04, 2019 12:32 pm

MySDK->MyLib->nvs_flash-> compilation success and i get libmylib.a from build

MyApp->libMyLib.a -> compilation error undefined reference to nvs_flash_init() etc.

Code: Select all

idf_component_register(SRCS Main.cpp
                    INCLUDE_DIRS REQUIRES nvs_flash MyMainLib log)

add_library(MyLib STATIC IMPORTED)

set_target_properties(MyLib PROPERTIES IMPORTED_LOCATION  ../../components/CustomStatic_LIB/lib MyLib.a)

target_link_libraries(${COMPONENT_LIB} PUBLIC  MyLib )
When I look at the build.ninja file /build /build.ninja





generated this code but libMyLib.a end of the line
