[CMake] Write CMakeLists.txt for this C++ program

[dexter810]

*Approach 1:*
CMakeLists.txt:

cmake_minimum_required(VERSION 3.6)
project(main CXX C)

add_executable(main main.cpp)

target_include_directories(main PRIVATE
                include build/deps/yara/src/yara/libyara/include) 


 target_link_libraries (main
                -Lbuild/src/ -Lbuild/deps/yara/src/yara/libyara/.libs
                yaracpp yara pthread ssl crypto) 


I got:
*cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX="$(pwd)/install" ..*

add_executable(main main.cpp)

add_library(yaracpp STATIC IMPORTED)

The libraries that I'm trying to link are actually static libraries and from
the link that you gave in the above answer, I encountered:
https://cmake.org/cmake/help/latest/command/target_link_libraries.html
where I tried giving this approach:
*
Approach 3*
CMakeLists.txt:
cmake_minimum_required(VERSION 3.6)
project(main CXX C)

add_executable(main main.cpp)

target_include_directories(main PRIVATE
                include build/deps/yara/src/yara/libyara/include) 


 target_link_libraries (main
                -Lbuild/src/libyaracpp.a
-Lbuild/deps/yara/src/yara/libyara/.libs/libyara.a
                yaracpp yara pthread ssl crypto) 



I got:
*
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX="$(pwd)/install" ..*

Also, inside target_link_libraries() irrespective of putting -lyaracpp and
-lyara or yaracpp and yara, I got the same errors.
