Can't link c++ libraries using CMAKE and make install - c++

Question

I am having a problem linking two libraries using CMake on linux (ubuntu). I have the following CMake setup.
cmake_minimum_required(VERSION 3.3)
project(lib1)
set(SOURCE_FILES
source_1.cpp)
# set library output directory
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ../build/)
# Base directory relative to which all includes are
set(BASE_DIR ../)
#include base directory
include_directories ("${BASE_DIR}")
# create a shared library
add_library(lib1 SHARED ${SOURCE_FILES})
# make install target
install(TARGETS lib1 DESTINATION /usr/local/lib)
For Library 2 we have
cmake_minimum_required(VERSION 3.3)
project(lib2)
set(SOURCE_FILES
source_2.cpp)
set(BASE_DIR ../)
#include base directory
include_directories ("${BASE_DIR}")
# create a shared library
add_library(lib2 SHARED ${SOURCE_FILES})
# include lib1 library
target_link_libraries(lib2 PUBLIC lib1)
install(TARGETS lib2 DESTINATION /usr/local/lib)
Running these with
cmake_minimum_required(VERSION 3.3)
project(all)
add_subdirectory(lib1)
add_subdirectory(lib2)
creates liblib1.so and liblib2.so. liblib2.so depends on liblib1.so (ldd liblib2.so gives the link to liblib1.so in the CMAKE_LIBRARY_OUTPUT_DIRECTORY directory.)
After running
make install
I get
-- Install configuration: "Release"
-- Up-to-date: /usr/local/lib/liblib1.so
-- Installing: /usr/local/lib/liblib2.so
-- Set runtime path of "/usr/local/lib/liblib2.so" to ""
and in /usr/local/lib liblib2.so is no longer linked to liblib1.so.
I tried many reworkings of my cmake file, (e.g. using :
set(CMAKE_INSTALL_RPATH "/usr/local/lib")
set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
but nothing seemed to help. Anyone can explain me how to get the libraries to link after make install?
I did run ldconfig manually, but no luck. /usr/local/lib is also part of ld.conf and I am running ubuntu 16.04.
