According to CMake's manual this var is used by FIND_PATH and FIND_FILE.

I search the CMAKE Sourcecode, it seems only useful in FIND_PATH command.

It works fine for me. And the paths defined in CMAKE_INCLUDE_PATH are
searched by default so you needn't pass it to FIND_PATH explicitly.

if we use it like $ENV{CMAKE_INCLUDE_PATH}, it is a normal environment

By default FIND_PATH use both CMake var CMAKE_INCLUDE_PATH and the env var
CMAKE_INCLUDE_PATH to search files.

We can define anyname like this.
