如何在MinGW / MSYS2上安装静态libz.dll.a，libssl.dll.a等？

Question

我正在项目的链接过程中获取此信息（使用cmake编译）：

[100%] Linking CXX executable roosek2.exe
/usr/lib/gcc/x86_64-pc-msys/9.1.0/../../../../x86_64-pc-msys/bin/ld: cannot find -lC:/msys64/mingw64/lib/libz.dll.a

当我在MinGW shell中使用MSYS2中的静态qt5进行编译时，会发生这种情况。这是我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.5)

project(roosek2 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)


find_package(Qt5 COMPONENTS Core Quick REQUIRED)

add_executable(roosek2
  main.cpp
  qml.qrc
  ImageStream.cpp
  YuvUtils.cpp
  CameraView.cpp
)

add_library(ctmedia_codec MODULE IMPORTED)
add_library(ctstream MODULE IMPORTED)
add_library(maincore MODULE IMPORTED)

#link_directories(${CMAKE_CURRENT_SOURCE_DIR}/win_bin/lib/x64)
set_target_properties(ctmedia_codec PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/win_bin/lib/x64/CTMedia.lib)
set_target_properties(ctstream PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/win_bin/lib/x64/CTStream.lib)
set_target_properties(maincore PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/win_bin/lib/x64/WPMainCore.lib)

include_directories("include")
target_compile_definitions(roosek2
  PRIVATE $<$<OR:$<CONFIG:Debug>,$<CONFIG:RelWithDebInfo>>:QT_QML_DEBUG>)
target_link_libraries(roosek2
  PRIVATE Qt5::Core Qt5::Quick ctmedia_codec ctstream maincore)

如何安装这些库？为什么需要它们？我真的需要它们吗？

安装这些软件包：

• 对于X86_64（64位）：

pacman -S mingw-w64-x86_64-openssl mingw-w64-x86_64-zlib mingw-w64-x86_64-zstd

• 对于X86（32位）：

pacman -S mingw-w64-i686-openssl mingw-w64-i686-zlib mingw-w64-i686-zstd
