[CMake] Is this the rigth way to build a shared library?

[dexter810]

This is my CMakeLists.txt which is successfully building a shared library, I
just wanted to confirm if it's the right way and it: 

cmake_minimum_required(VERSION 3.6)
project(main)



include_directories(
        ${CMAKE_CURRENT_SOURCE_DIR}/include
       
${CMAKE_CURRENT_SOURCE_DIR}/build/deps/yara/src/yara/libyara/include)

add_library(main SHARED main.cpp)


link_libraries (
        -L${CMAKE_CURRENT_SOURCE_DIR}/build/src/
        -L${CMAKE_CURRENT_SOURCE_DIR}/build/deps/yara/src/yara/libyara/.libs
    yaracpp yara pthread ssl crypto)




When I do ldd libmain.so I get: 

   linux-vdso.so.1 (0x00007ffee6583000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x00007f7e1be18000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00007f7e1bc00000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7e1b80f000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f7e1b471000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f7e1c3a4000)



CMakeLists.txt for creating a successfully running executable: 
cmake_minimum_required(VERSION 3.6)
project(main CXX C)

add_executable(main main.cpp)

target_include_directories(main PRIVATE
        ${CMAKE_CURRENT_SOURCE_DIR}/include
       
${CMAKE_CURRENT_SOURCE_DIR}/build/deps/yara/src/yara/libyara/include)

target_link_libraries (main
        -L${CMAKE_CURRENT_SOURCE_DIR}/build/src/
        -L${CMAKE_CURRENT_SOURCE_DIR}/build/deps/yara/src/yara/libyara/.libs
    yaracpp yara pthread ssl crypto)

on doing ldd main, I got: 

    linux-vdso.so.1 (0x00007ffe723d4000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007fc0c644b000)
    libcrypto.so.1.1 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1
(0x00007fc0c5f80000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x00007fc0c5bf7000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fc0c5859000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00007fc0c5641000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc0c5250000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fc0c68d6000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fc0c504c000)
