I want to install EMSDK for WASM compilation but EMSDK installation fails.
I’ve already installed Cmake (3.14.0-rc1 also tried 3.5.2 then) on Ubuntu 16.
When I run ./emsdk install sdk-incoming-64bit binaryen-master-64bit it fails:
CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage CMake Error: CMAKE_ASM_COMPILER not set, after EnableLanguage -- Configuring incomplete, errors occurred!

You are probably missing make as cmake is complaining that there is no make program. Try sudo apt-get install build-essential
