Subject: Update python lookup in CMakeLists.txt to match build.(sh|cmd) (#22145)
X-Git-Tag: accepted/tizen/unified/20190813.215958~173
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e7c6f87f54be723724a4c996d815d59b515b01a6;p=platform%2Fupstream%2Fcoreclr.git

Update python lookup in CMakeLists.txt to match build.(sh|cmd) (#22145)

Use the same logic that's used in build.sh/build.cmd to lookup python:
first search for `python3`, then fall back to `python2` and finally to
`python`.
