I'm trying to build some code I got from GitHub using CMake, but keep getting the followings errors:
CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER
CMake Error: Could not find cmake module file:/golang/project/src/github.com/devsisters/goquic/libquic/build/debug/CMakeFiles/2.8.11/CMakeCCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_CXX_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

CMake Error: Could not find cmake module file:/golang/project/src/github.com/devsisters/goquic/libquic/build/debug/CMakeFiles/2.8.11/CMakeCXXCompiler.cmake
-- Configuring incomplete, errors occurred!
How do I set these variables correctly?
I used a ./build_libs.sh
file that came with the GitHub code to build this.
The script you are executing uses the CMake Ninja generator. For that to work you need Ninja on the path. On most Linux distributions you can install it from a package.
Ubuntu: ninja-build
openSUSE: ninja
If you can't find it for your distribution, you have to download it and add its location to the path
environment variable.
