Buill Abseil on CI service

[uilianries]

Hi!

It would be nice if it were possible to build Abseil for each new push to be sure of his integrity and reliability .

There are a wide variety of free services for open source projects, which cover most market platforms:

• Travis CI
• Appveyor
• Circle CI
• Azure DevOps

You could build Abseil on Linux, OSX and Windows, for example.

Regards!

This is already happening in an internal change. We will be turning on Travis and Appveyor soon, we're just making sure that we have a coherent plan for CI moving forwards and making sure we do all our due diligence to not leak internal stuff.

seems related to #109 and PR #197 ...

I guess

abseil-cpp/absl/copts/GENERATED_AbseilCopts.cmake

Lines 206 to 208 in 93dfcf7

	list(APPEND ABSL_MSVC_LINKOPTS
	"/ignore:4221"
	)

just break windows build 🎆
https://ci.appveyor.com/project/Mizux/cmake-abseil/builds/23528461/job/jrp21qm2jcemx1bf#L185
note: take a look at https://github.com/Mizux/cmake-abseil/tree/install to see how abseil-cpp could be tested against numerous linux distro and windows...

Seems it won't happen...

Abseil has decided that we're not going to take on travis and appveyor currently, so I will close this > > issue. Please feel free to reopen in the future.
