按下面的方法写,是可以调用simple_math库
add_library(simple_math STATIC
"math_lib/myadd.c"
"math_lib/mysub.c")

target_link_libraries(${COMPONENT_LIB} PUBLIC "simple_math")

但是把add_library删除只保留target_link_libraries就找不到simple_math库
target_link_libraries(${COMPONENT_LIB} PUBLIC "simple_math")
报错:ld.exe: cannot find -lsimple_math
实际上在build\esp-idf\main\路径下有已经生成的libsimple_math.a,该怎样找到它呢?

库生成了,也放到了main路径下,链接时找不到,这是什么原因?
GATT_SERVER/main/libsimple_math.a

GATT_SERVER/main/CMakeLists.txt 书写如下
target_link_libraries(${COMPONENT_LIB} PUBLIC "simple_math")
