The backtraces for some of the commands incorrectly come from the
target's directory instead of the caller's directory. Expect the
incorrect backtraces in test results for now.
Increase the minimum required version of CMake in the test case
to enable policy CMP0079 to support cross-directory calls.
Issue: #23873
Add a file-based API that clients may use to get semantic information
about the buildsystem that CMake generates. Clients will write query
files under a designated location in the build tree, and CMake will
write reply files for clients to read.
Start with support for shared stateless query files. These allow
clients to share requests for major object versions and get all those
recognized by CMake. Once any client has written a shared request to a
build tree it will persist. Other clients will not need to overwrite
the request (since it is stateless) and should not remove it either.
For now we add only an undocumented object kind to use for testing the
query and reply infrastructure. Object kinds providing real semantic
information will be added later.
