我在 Raspbian Stretch 上有这个设置：
pi@raspberry:~/rtest $ tree /home/pi/rtest/
/home/pi/rtest/
├── build
├── CMakeLists.txt
└── main.cpp
1 directory, 2 files
pi@raspberry:~/rtest $ g++ --version | head -1
g++ (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516
这些文件是这些：
CMakeLists.txtset(restbed_BUILD_SSL OFF)cmake_minimum_required(VERSION 3.14)
SET(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_C_STANDARD 11)
set(CMAKE_CXX_STANDARD 14)
set(FETCHCONTENT_QUIET FALSE)
include(FetchContent)
FetchContent_Declare(

)
set(restbed_BUILD_SSL OFF)
set(restbed_BUILD_TESTS OFF)

set(${PROJECT_NAME}_sources

target_include_directories(${PROJECT_NAME} PUBLIC

)
...和
main.cpp#include <restbed>
int main(void) {
return 0;
}
然后我这样做：
pi@raspberry:~/rtest $ cd ~/rtest/build

因此，尽管有警告，我的可执行文件仍然可以编译 - 但随后，构建过程想要构建
_deps/restbed-build/CMakeFiles/restbed-static.dir/source/corvusoft/restbed/detail/http_impl.cpp.oerror: expected constructor, destructor, or type conversion before ‘DEPRECATEDIN_1_2_0’我已经看到 DEPRECATEDIN_1_2_0() 太急切了·问题#6814·openssl/openssl，但我真的不知道我可以/应该做什么来摆脱错误。
我想，最简单的方法就是在没有 SSL 的情况下进行编译 - 但是这个
restbed/detail/http_impl.cpp.oset(restbed_BUILD_SSL OFF)那么在这种情况下我可以从 CMake 做些什么来让 Restbed 和/或 openssl 进行编译呢？我现在可以没有 https （openssl 部分），但我真的不知道如何在 CMakeLists.txt 中指定它......
好吧，得到了一些东西 - 对我来说有点令人惊讶，我需要做的就是在我的主
restbedcmakepi@raspberry:~/rtest/build $ ~/src/cmake-3.28.1/bin/cmake ../ -DBUILD_SSL=NO -DBUILD_TESTS=NO -DCMAKE_BUILD_TYPE=Debug
...然后它们以某种方式传播到休息床，并且
restbed/detail/http_impl.cpp.o我可能还应该使用缓存的 CMake 变量 - 但现在没有时间测试......
