我刚刚将我的CMake从2.8升级到3.2。
它在CMake 2.8中的功能就像一个魅力,但在升级后,它失败了。
我正在尝试使用ExternalProject_Add()
CMake功能构建第三方库。
ExternalProject_Add(
luacov
URL https://github.com/keplerproject/luacov/archive/v0.7.tar.gz
DOWNLOAD_DIR ${EXTERNAL_PROJECT_DOWNLOAD_DIR}
CMAKE_ARGS -DCMAKE_TOOLCHAIN_FILE=${MY_TOOLCHAIN_FILE}
SOURCE_DIR ${EXTERNAL_PROJECT_SRC_DIR}/luacov
BINARY_DIR ${EXTERNAL_PROJECT_BUILD_DIR}/luacov
UPDATE_COMMAND ""
PATCH_COMMAND ""
)
我的观察:
GIT_REPOSITORY
选项,ExternalProject_Add()
允许http
和https
协议下载外部项目。URL
选项,ExternalProject_Add()
仅允许http
,但不允许https
协议下载外部项目。问题:
有没有办法使用https
协议下载和构建外部项目?
错误:

问题可能是默认情况下,CMake附带的CURL库不支持SSL。我不得不用以下代码编译cmake:
front-end:
build: .
ports:
- "4200:4200"
volumes:
- ./code:/code
......这很有效,因为我的系统卷曲有SSL支持。

它对我有用的是:
更新openssl
sudo apt-get install openssl libssl-dev
修改bootstrap文件以启用CMAKE_USE_OPENSSL。将此{{3}}替换为:
cmake_options="-DCMAKE_BOOTSTRAP=1 -DCMAKE_USE_OPENSSL=ON"
在cmake文件夹中正常运行bootstrap脚本
/@path_to_cmake/bootstrap

在我的ExternalProject_Add()
中,我使用GIT_REPOSITORY
选项URL
。{/ p>
#URL https://github.com/keplerproject/luacov/archive/v0.7.tar.gz
GIT_REPOSITORY https://github.com/keplerproject/luacov.git
luacov
下载并成功构建。
对于任何https
协议,请使用DOWNLOAD_COMMAND
函数的ExternalProject_Add()
选项。
DOWNLOAD_COMMAND wget https://github.com/keplerproject/luacov/archive/v0.7.tar.gz
并按预期工作。
感谢。

我在计算机中构建库时遇到同样的问题,其中CMake不支持https协议。
我必须按照@ dekkard评论的建议选择-DCMAKE_USE_OPENSSL = ON来自己构建cmake。

对于CMake 3.8.0,这对我有用:
安装/更新openssl:
yum install openssl openssl-devel
通过Brad King调整CMake forum reply的解决方案:
./configure --prefix=/software/cmake-3.8.0/ --parallel=${NPROC} -- \
-/DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_USE_OPENSSL:BOOL=ON
make -j ${NPROC}
make install
享受!

与Cmake 3.2.1一样,它按预期工作。
这是我的示例项目/ CMakeLists.txt:
PROJECT(TestDownload)
SET(CMAKE_CXX_COMPILER "/path/to/bin/g++")
SET(CMAKE_C_COMPILER "/path/to/bin/gcc")
SET(CMAKE_CXX_FLAGS "")
SET(CMAKE_C_FLAGS "")
cmake_minimum_required(VERSION 3.2)
include(ExternalProject)
ExternalProject_Add(

URL https://github.com/keplerproject/luacov/archive/v0.7.tar.gz

)
命令:
$ cd project
$ mkdir build && cd build
$ cmake ..
...
$ make all

我通常只会将URL从https修改为http。
