currently I’ve got the following project definition :

```auto
set(supported_languages "CXX OBJC OBJCXX")

project(
  myProj
  VERSION ${ver}
  LANGUAGES ${supported_languages})

```

where `supported_languages` is defined as string of parameters delimited by space (i.e. `CXX OBJC OBJCXX`)

However, it fails since cmake expect to get a list and this is the error I get

```auto
CMake Error: Could not find cmake module file: CMakeDetermineCXX OBJC OBJCXXCompiler.cmake

```

So I’ve tried to convert it to list `list(${supported_languages})` but it still doesn’t work.

I wonder what is the best practice to make it work ?

set(supported\_languages CXX OBJC OBJCXX)

or

set(supported\_languages “CXX;OBJC;OBJCXX”)

If you need the input to be space delimited, convert it to a cmake list with string replace command
