我想要在一个小型项目中集成 c++ 的 crypto++ 库。我目前使用 Windows 和 mingw64（本机）作为我的编译器和 cmake 来构建。
我的项目目录如下所示：
Project Root
|-sources
|-lib
|-crytopp-880 (Contains the CrytoPP library)
|-cryptopp-cmake (Contains the cmake files for it to work)
|-build
|-CMakeLists.txt
我使用指南通过 Crypto++ CMake 中的 cmake 构建和添加 crypto++。我的根 CMakeLists.txt 看起来像这样。
project(project_cipher)
add_subdirectory(sources build)
add_subdirectory(${PROJECT_SOURCE_DIR}/lib/cryptopp-880)
add_subdirectory(${PROJECT_SOURCE_DIR}/lib/cryptopp-cmake)
set(CRYPTOPP_SOURCES ${PROJECT_SOURCE_DIR}/lib/cryptopp-880)
include_directories(${PROJECT_SOURCE_DIR}/lib/cryptopp-880)
target_link_libraries(cipher cryptopp)
我将其作为 Powershell 命令运行：
cmake -G "MinGW Makefiles" .
输出是：

正如它所说，该文件夹缺少 CMakeLists.txt。所以，我添加了一个空白的。然后在运行相同的命令时，它显示：
=> Project : cryptopp-cmake v8.8.0
-- Crypto++ auto fetched at: E:/Programms/CODING PROJECTS/C++ Cypher Project/lib/cryptopp-cmake/cryptopp
fatal: not a git repository (or any of the parent directories): .git

我想静态且完全离线地添加库，并使用 readme.md 中给出的指南。然而，它仍然使用在线 git repo 来下载库。
如何以使用下载版本的方式进行设置，并在按预期构建后链接它？ （回购协议是这么说的）
