[CMake] PIE-pie_off and CMP0083-cmp0083_new fail for openSuse Leap 15.0

[Christoph Grüninger]

Dear CMake,
while trying to update the RPMs for openSuse with the Open Build
service, I stumbled upon a strange problem. Following the same spec file
for all target plattforms, CMake is first built and then the tests are
executed. The tests pass for different types of openSuse versions
(Factory, Tumbleweed, Leap 42.3, SLE 12 SP3) but fail for a single
version, openSuse Leap 15.0. I attached the output of the failing tests.
The failure is related to CMP0083 and PIE. But I cannot spot any
difference causing different test results.
Could someone advice how to track down the reason for my issue?

Bye,
Christoph
