jedi-cmake depends on C and C++ compilers when it doesn't

[climbfuji]

Description

If no language is specified in the CMake PROJECT configuration, the default is C CXX:

Line 8 in 40d521f:

 project( jedicmake VERSION 1.4.0 DESCRIPTION "JEDI CMake Toolkit" ) 

Maybe

project(jedicmake <other options> LANGUAGES NONE)

fixes this?

To Reproduce

Install jedi-cmake on a system where there is no default gcc/g++.

Expected behavior

If it doesn't depend on C/C++, then the cmake config should be fixed.

System, compiler, code, ...

Any
