Where is "cmake/CMakeExpandImportedTargets.cmake"? The upstream CMake module is in "Modules/" and has no get_target_property call on line 66.

This is in CMake'ified CPython, since the minimum required CMake is 2.8.6 and that module has been integrated only after 2.8.7, we have our own copy.

See https://github.com/davidsansome/python-cmake-buildsystem/blob/master/cmake/CMakeExpandImportedTargets.cmake [^]

Okay, we can fix the equivalent line in the upstream copy of the module.

FYI, since 2.8.11 the module is not necessary:

 Handle targets in the LINK_LIBRARIES of try_compile.

This should fix it:

 CMakeExpandImportedTargets: Do not read property on non-target
