使用 ldd $(which cmake)

没有 libcurl.so.4=>/usr/lib/x86_64-linux-gnu/libcurl.so.4

解决方法一：

cmake编译默认是不加curl的,需要重装cmake

git clone -b v3.10.2 https://cmake.org/cmake.git cmake

cd cmake

./bootstrap --system-curl

make

sudo make install

或者

./configure --prefix=/software/cmake-3.10.2/ --parallel=${NPROC} -- \ -/DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_USE_OPENSSL:BOOL=ON

make -j ${NPROC}

make install
