curl - CMAKE_USE_SYSTEM_CURL 已打开但未找到 curl

Question

我正在尝试使用 system-curl 安装 cmake，使用 ./bootstrap --system-curl，如 here 所示.这样做，我得到了:

    -- Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR) 
CMake Error at CMakeLists.txt:413 (message):
  CMAKE_USE_SYSTEM_CURL is ON but a curl is not found!
Call Stack (most recent call first):
  CMakeLists.txt:682 (CMAKE_BUILD_UTILITIES)


-- Configuring incomplete, errors occurred!

Error when bootstrapping CMake:
Problem while running initial CMake

Answer 1

对我来说，运行 ./bootstrap --no-system-curl 导致在 open-cv 上运行 cmake 时出错，因为找不到 https 协议(protocol)。所以我需要让 ./bootstrap --system-curl 运行。

解决方案是安装 curl 开发依赖项。 cmake 需要这些，而不仅仅是 curl。

我跑了:

sudo apt-get install curl
sudo apt-get install libssl-dev libcurl4-openssl-dev
