INTERFACE_LIBRARY targets may only have whitelisted properties.

[Finkman]

The Setup

I use pugixml (v1.13) as an in-source library in folder lib/pugixml. The entire project is build with BUILD_SHARED_LIBS=OFF.

I am using cmake 3.18.2

The Error

When I configure the project, I receive the error from cmake:

CMake Error at libs/pugixml/CMakeLists.txt:155 (add_library):
  INTERFACE_LIBRARY targets may only have whitelisted properties.  The
  property "INCLUDE_DIRECTORIES" is not allowed.

NOTE: This also happens with current master ( 1dc3266 )

Expectation

cmake configure step executes without an error.

Given the amount of issues we've had last time with aliases etc. I'm very worried about merging any changes that change the existing alias structure at all. See issues linked from #392.

Is this error specific to CMake 3.18?

Looking at the diff from 1.11.4, I'm not sure I undestand if anything changed since then to produce this error. Notably, CMakeLists.txt does not add include directories for pugixml target itself. Does your CMake setup interact with pugixml targets in any way besides just including the pugixml folder?

This also happend with CMake 2.25.
But,... my guess was kind of misleading. The issue was caused by an odd mistake on my side where two different pugixml-folders interfere each other. With this, the second was trying to set properties on the target that has been defined before.
Sorry for the noise.
