Now we see even more syntax. Strings are quoted, white space doesn't matter [^3], and the name of the project is the first argument (positional). All the keyword arguments here are optional. The version sets a bunch of variables, like `MyProject_VERSION` and `PROJECT_VERSION`. The languages are C, CXX, Fortran, and CUDA (CMake 3.7+). `C CXX` is the default. In CMake 3.9, `DESCRIPTION` was added to set a project description, as well. The documentation for «command:`project`» may be helpful. Now we see even more syntax.

CMake doesn't care about white space, and you can add comments with the `#` character, but never put a comment inside the function call parenthesis. You can add [comments](https://cmake.org/cmake/help/latest/manual/cmake-language.7.html#comments) with the `#` character. CMake does have an inline syntax for comments too, but it is rarely needed, as whitespace doesn't matter.
