Fix the condition added by commit fada8cbfd6 (CheckLanguage: Report
CMAKE_CUDA_HOST_COMPILER if needed for compilation, 2019-05-31,
v3.15.0-rc1~12^2) to activate CUDA-specific logic. The old condition
had worked in our test suite only by accident because the loop variable
used in the test happened to be the name and value that the old
condition used! Update the test to use a different name.

When the path to a header file is specified using a generator
expression, evaluation of the genex must produce an absolute path.
Update our documented example and add a test covering the case.

Since commit 1c2d031cbd (Add -E cmake_llvm_rc to preprocess files for
llvm-rc, 2020-01-14, v3.17.0-rc1~24^2) with llvm-rc we explicitly
preprocess RC source files and then compile separately without -I flags.
This broke cases where the RC source references data files adjacent to
itself or in the include path.
This change adds the expansion of the include paths when calling the
llvm-rc in order for the resource files to be picked up correctly by
llvm-rc. Since the RC compiled file is first preprocessed, the file
being compiled by llvm-rc resides in the build directory. In order for
llvm-rc to find the resource data specified relative to the .rc file
being compiled, the source file path is preppended in the include list
so that the original source path takes priority over all the other
includes paths specified.
A space was added in the CMAKE_INCLUDE_FLAG_RC to make the include
directive work properly for llvm-rc. Checks on the rc.exe showed that
the syntax change doesn't affect it's proper operation.

Since commit b8626261e9 (Precompile headers: Add methods to generate PCH
sources, 2019-07-13, v3.16.0-rc1~182^2~4) we look up source files for a
target using an upper-case configuration even though an original-case
name is sufficient. Since commit 36ded610af (PCH: Generate sources
during Compute step, 2019-10-05, v3.16.0-rc1~2^2) the source file lookup
is the first time we compute many on-demand structures that depend on
the configuration name. This caused the `$<CONFIG>` generator
expression to evaluate to the upper-case configuration name in some
cases where we used original-case before.
Fix this by switching the source file lookup to the original-case config
name. Add a test covering the symptom that led to the discovery of this
problem.

Since commit d1976cd1f2 (CTest: Fix timeout when grandchild keeps pipes
open, 2020-01-13, v3.17.0-rc1~169^2) we no longer hang, but the test
duration we report after the timeout is the amount of time the immediate
child ran before exiting. Fix the logic to instead report the actual
amount of time we spent monitoring the test before the timeout.

CMake 3.16 and below allow multiple `export()` calls with the same output
file even without using `APPEND`. The implementation worked by accident
by leaking memory. Refactoring in commit 5444a8095d (cmGlobalGenerator:
modernize memrory managemenbt, 2019-12-29, v3.17.0-rc1~239^2) cleaned up
that memory leak and converted it to a use-after-free instead.
The problem is caused by using the `cmGlobalGenerator::BuildExportSets`
map to own `cmExportBuildFileGenerator` instances. It can own only
one instance per output FILE name at a time, so repeating use of the
same file now frees the old `cmExportBuildFileGenerator` instance
and leaves the pointer in the `cmMakefile::ExportBuildFileGenerators`
vector dangling. Move ownership of the instances into `cmMakefile`'s
vector since its entries are not replaced on a repeat output FILE.
In future work we should introduce a policy to error out on this case.
For now simply fix the use-after-free to restore CMake <= 3.16 behavior.

In commit 3dab4682f6 (FindPython: reduces consumption of resources,
2020-02-10, v3.17.0-rc1~11^2) we accidentally broke the python
executable version validation when the "LOCATION" strategy is used
with the plain `FindPython` module. Fix the logic and add test
cases covering those combinations.

The properties added by commit 4a62e3d97c (macOS: Add
OSX_COMPATIBILITY_VERSION and OSX_CURRENT_VERSION properties,
2020-01-24, v3.17.0-rc1~80^2~1) are general-purpose for all platforms
using Mach-O formats and not just on OS X. Rename them accordingly.
The properties are new to the CMake 3.17 release so we can rename
them without compatibility concerns.
Fixes: #20442
If cross-config mode is used, and a target depends on another target
as well as a custom command, we don't want the custom command to also
depend on the depended target, as that would build targets unnecessarily.
Fix this behavior.
We may want to enable these variables later on with specific
semantics. To avoid breaking backwards compatibility, make it an
error to use them for now.
Also rename `..._DEFAULT_BUILD_FILE_CONFIG` to `..._DEFAULT_BUILD_TYPE`.
These name changes make the variables meaningful for future use by other
generators.
