Simple CMakeLists gotcha

If you are messing around with CMakeLists for your project, you might try this:

project (myapp 
            DESCRIPTION "messing around with Urho3D"
            LANGUAGES CXX)

But then you will get the error

CMake Error at CMake/Modules/CheckCompilerToolchain.cmake:194 (message):
  Could not check compiler toolchain as it does not handle '-E -dM' compiler
  flags correctly

It’s because specifying the languages explicitly means they won’t be implicitly found… and you need C.

Solution:

project (myapp 
            DESCRIPTION "messing around with Urho3D"
            LANGUAGES C CXX)
