[CMake] Selecting INSTALL target in Visual Studio Configuration by default

[Paul Baumer]

Thanks for your help. I have just tried this. But there is a cyclic
dependency issue.

install_after_all calls "install" which depends on "ALL_BUILD" and tries to
build "install_after_all".

Possible solutions:
a. break the "install" - "ALL_BUILD" dependency. This sounds kind of
unhealthy.
b. remove "install_after_all" from ALL_BUILD. What would be the appropriate
way of doing this?

Again, thanks for your help!.

Paul
