Configuration of CMake throws error "No CMAKE_CXX_COMPILER could be found" - CMake log inside

[Ajorona]

Hello All,

I am trying to configure Qt 5.7 on my PC running ubuntu 17.10 "artful". gcc and g++ are installed. when I run the "hello world" test application a CMake log is printed to console. I am not sure what steps I need to take or what information I need to provide in order to get Qt 5.7 to run successfully on my machine.

  to the compiler, or to the compiler name if it is in the PATH.

Hi and welcome to devnet,

How did you install the compilers ?
