./schema/generate.sh

Outputs:

/schema/generate.sh ==> cd schema && ./generate.sh

[shinexia]

/schema/generate.sh ==> cd schema && ./generate.sh

same results

build succeed on centos 7 (docker), with:
cmake version 2.8.12.2
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)

but still failed on ubuntu 18.04

you could try export CMAKE_ROOT=/path/to/where_cmake_installed

but re-installing cmake is more recommended.

fixed after running this:
sudo apt install extra-cmake-modules

Hi, sry to disturb. A similar problem occurs in my case, and the following is the output:

I have installed extra-cmake-modules, but no changes. Anybody help me out? Thx.

Unix Makefiles

perhaps make is not installed in your system? try sudo apt-get install make.

Thx. I have installed the make, but the problem remains. Anyway, I read the script generate.sh, implement the commands one by one, and then success to complete this step. A little strange, there may be some points i missed.
