[CMake Error] newer versions of CMake complain about duplicate else

[moriarty]

Newer versions of CMake complain:

-- Looking for ccache - found (/usr/bin/ccache)
CMake Error at cmake/OpenCVCompilerOptions.cmake:21 (else):
  A duplicate ELSE command was found inside an IF block.
Call Stack (most recent call first):
  CMakeLists.txt:495 (include)

This has already been patched upstream master and back-ported to 2.4.

opencv/opencv#9408

How does one submitted a PR to apply the same patch?

[moriarty]

My question should have been "to where" not "how does" one submit a PR.

Was this resolved with the update to 3.3.1?

[moriarty]

Unfortunately I'm in the process of moving and don't have the desktop with me where this error occurred.

I will try to check as soon as possible.

Hi,
can be reproduced with cmake version 3.11.2 (i.e on debian buster) if ccache is used
