[CMake] project command not working, when used via macro (from an included file)

[CHEVRIER, Marc]

May be using keyword NO_POLICY_SCOPE in include command will solve your problem…

ajneu,

The call to project(...) needs to be explicit.  See https://cmake.org/cmake/help/v3.5/command/project.html:

The top-level CMakeLists.txt file for a project must contain a literal, direct call to the project()<https://cmake.org/cmake/help/v3.5/command/project.html#command:project> command; loading one through the include()<https://cmake.org/cmake/help/v3.5/command/include.html#command:include> command is not sufficient.

Hi,

when calling `project`
...as seen here
... https://github.com/ajneu/cmake_project_via_macro/blob/5972c7362e11fdbaa09d9defe8cca2dcea79e606/CMakeLists.txt#L33
everything is ok.


BUT when calling `project` via a macro (that was included)
... as seen here
... https://github.com/ajneu/cmake_project_via_macro/blob/master/CMakeLists.txt#L33
the behaviour is not as expected.

Why?

(Details are here: https://github.com/ajneu/cmake_project_via_macro)


Is this a bug?

Thanks
ajneu
