[Pkg-cmake-team] Bug#867514: python2.7/cmake: find_package called with invalid argument "2.7.13+"

[Adrian Bunk]

Source: python2.7
Version: 2.7.13-3
Severity: serious
Control: affects -1 cmake src:libsolv

mips* are the only release architectures where python2.7 2.7.13-3
built successfully, on all other architectures it FTBFS (#866800).

This makes the following libsolv FTBFS appear only on mips*:

It is not clear to me whether the bug is in python2.7
or cmake (cmake maintainer Cc'ed).
