Also extend our integration test double inclusion. It will still not catch this case, because that requires `cmake_minimum_required(VERSION 3.18)` or higher. Fixes: ``` CMake Error at .../lib/cmake/libssh2/libssh2-config.cmake:8 (add_library): add_library cannot create ALIAS target "libssh2::libssh2" because another target with the same name already exists. Call Stack (most recent call first): CMakeLists.txt:24 (find_package) CMake Error at .../lib/cmake/libssh2/libssh2-config.cmake:13 (add_library): add_library cannot create ALIAS target "Libssh2::libssh2" because another target with the same name already exists. Call Stack (most recent call first): CMakeLists.txt:24 (find_package) ``` Test to reproduce: ```cmake cmake_minimum_required(VERSION 3.18) # must be 3.18 or higher project(test) find_package(libssh2 CONFIG) find_package(libssh2 CONFIG) # fails add_executable(test main.c) target_link_libraries(test libssh2::libssh2) ``` Ref: https://cmake.org/cmake/help/latest/release/3.18.html#other-changes Ref: https://cmake.org/cmake/help/v3.18/policy/CMP0107.html Assisted-by: Kai Pastor Assisted-by: Harry Mallon Ref: https://github.com/curl/curl/pull/11913 Closes #1216
