Findopenssl.cmake 无法找到 OpenSSL,编译 restbed,C++
Findopenssl.cmake fails to find OpenSSL, compiling restbed, C++
我正在尝试在 Debian 9.7 上使用 cmake 3.7.2 来编译 restbed,一个用于 Web 服务的C++框架。
我按照自述文件的说明进行操作。它们很简单。
git clone --recursive https://github.com/corvusoft/restbed.git
mkdir restbed/build
cd restbed/build
cmake [-DBUILD_SSL=NO] ..
make install
make test
但是我在运行cmake时出现以下错误:
-- Found ASIO include at: /home/ben/Workspaces/C_Experiments/restbed/dependency/asio/asio/include
-- Found Catch include at: /home/ben/Workspaces/C_Experiments/restbed/dependency/catch/single_include
CMake Error at cmake/Findopenssl.cmake:23 (message):
Failed to locate OpenSSL dependency. see restbed/dependency/openssl;
./config shared; make all
Call Stack (most recent call first):
CMakeLists.txt:47 (find_package)
所以我检查了Findopenssl.cmake,发现它正在许多地方寻找图书馆。
find_library( ssl_LIBRARY_STATIC libssl.a ssleay32.lib HINTS "${PROJECT_SOURCE_DIR}/dependency/openssl/out32dll" "${PROJECT_SOURCE_DIR}/dependency/openssl" "/usr/local/opt/openssl/lib" "/usr/lib" "/usr/local/lib" "/opt/local/lib" )

我也找不到这些文件。我已安装 openssl 版本,版本 1.1.0
我在这里错过了什么明显的东西?
谢谢
尝试使用不带括号的 cmake
命令:
cmake -DBUILD_SSL=NO ..
Brady Dean是对的,我只安装了openssl,而不是libssl-dev。
