Summary0013945: unhelpful error (and build failure) when project name has space in it
Descriptionwhen the project() command is given with a project name with a space in it, the error report complains of"

CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

and refuses to build, not indicating that the project name is invalid.
Steps To ReproduceRun cmake on a directory with this CMakeLists.txt:

"
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(proj separated)
"

and the output should be similar to:

CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_separated_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

Not sure if that can be fixed. You asked for a project named proj using the language called separated. I suppose the error message might say something about failing to enable or recognize the language "separated". But, CMake is a space separated language and this is documented in the project command.

Ah, that makes sense. I filed it just because I had done it by accident and it wasn't immediately obvious what I had done wrong.

I think it would be clearer if the command were set up
project(name LANGUAGES lang_1 lang_2 ...)
but this would not be backwards-compatible and so is probably not worth it.
