[CMake] cmake 3.7.2 centos 7 :: kwsys.testSystemTools (Failed)

[Chuck Atkins]

Hi Adrian,

I'd suggest taking the issue up with the package maintainer.  The upstream
source for CMake 3.7.2 configures, builds, and passes all tests on EL7 so
the problem seems to lie in how the RPM SPEC file is driving the build.
