cmake source install as follows:

0 cd ~

1 wget https://cmake.org/files/v3.5/cmake-3.5.2.tar.gz

2 tar xvf cmake-3.5.2.tar.gz

This worked for me  then:

3 cd cmake-3.4.3

4 ./bootstrap --prefix=/usr

这一步很关键，如果没有指定prefix，后面使用时会报错Could not find CMAKE_ROOT

5 make

6 sudo make install

check:

cmake --version

[root@localhost cmake-3.5.2]# cmake --version

cmake version 3.5.2
