CMake: build shared lib from src and other static libs - c++

Question

\- lib
CMakeLists.txt
libA.a
libB.a
\- src
\- mod1
\- mod2
\- inc
\- mod1
\- mod2
\- libA
\- libB
\- examples
\- common_inc // common includes for all examples
\- my_executable
CMakeLists.txt
\- src
\- inc
src contains .cpp files for mod1 and mod2, both depend on libA, libB, inc contains headers for libA, libB, and for mod1 and mod2
The question is:
I want to make one shared library which contains libA.a, libB.a and also my src (mod1 and mod2), how I can achieve that?
Is there any other way besides creating static lib (lets call it libMy) from mod1 and mod2 and then link all 3 libs (libMy, libA, libB) into one shared library?
I came up with following CMakeLists.txt but it cannot find -llibA and -llibB
cmake_minimum_required (VERSION 3.5)
project (libMy CXX)
set (CMAKE_CXX_STANDARD 14)
set (SRC
"src/mod1/a1.cpp"
"src/mod2/a2.cpp"
)
set (INC
"inc/mod1/a1.hpp"
"inc/mod2/a2.hpp"
"inc/lib1/libA.hpp"
"inc/lib2/libB.hpp"
)
add_library(libMy STATIC ${SRC} ${INC})
target_include_directories(libMy PUBLIC inc)
add_library(master_library SHARED
dummy.cpp
)
target_link_libraries(master_library libMy)
target_link_libraries(master_library -lpthread)
target_link_libraries(master_library libA.a)
target_link_libraries(master_library libB.a)
UPDATE
Thanks to #Tsyvarev I managed to solve this problem. But there is another one...
When I try to link my shared library into my_executable I get undefined reference error, here is full error message:
