This reverts commit v3.8.0-rc1~305^2 (Remove CTestTestfile.cmake when
BUILD_TESTING is OFF, 2016-11-14). It breaks projects that never enable
testing but create their own `CTestTestfile.cmake` manually instead.
Previously we had a two issues when building cuda executables
that required separable compilation. The first was that we didn't
propagate FLAGS causing any -arch / -gencode flags to be dropped, and
secondly generators such as ninja would use the CXX language flags
instead of CUDA when the executable was mixed language.
4cc601f2 Help: Add release note for CUDA support
7b9131da CUDA: Add tests to verify CUDA compiler works properly.
9cf5b98d CUDA: Prefer environment variables CUDACXX and CUDAHOSTCXX.
a5e806b3 CUDA: Add support for CMAKE_CUDA_COMPILE_OPTIONS_VISIBILITY
d038559e CUDA: Add separable compilation support to the makefile generator.
43ce4414 CUDA: Add separable compilation support to the ninja generator.
4b316097 CUDA: Add support for the CUDA_SEPARABLE_COMPILATION target property
ae05fcc6 CUDA: Add LinkLineComputer that computes cuda dlink lines.
115269a8 CUDA: Refactor cmLinkLineComputer to allow for better derived children.
5dec4031 CUDA: Refactor CMakeCUDAInformation to prepare for separable compilation.
5b20d0ab CUDA: C++ compile features now enable cuda c++11 support.
489c52ce CUDA: Use the host compiler for linking CUDA executables and shared libs.
bbaf2434 CUDA: add support for specifying an explicit host compiler.
a92f8d96 CUDA: Enable header dependency scanning.
ec6ce623 CUDA: State that cuda has preprocessor output and can generate assembly.
4f5155f6 CUDA: We now properly perform CUDA compiler identification.

When disabling BUILD_TESTING after a previous configure, the
`CTestTestfile.cmake` was left unchanged. As a result, ctest would see
the tests while the user disabled testing. Now when BUILD_TESTING is
OFF any existing `CTestTestfile.cmake` is removed ensuring an empty test
list.

Port dependents to the new locations as needed.
Leave behind a cmState.h include in cmListFileCache to reduce noise. It
is removed in a following commit.
Add a factory function to cmLocalGenerator so that variableMappings can
be provided from it, and so that Ninja can always have a hard-coded
TargetImpLib.
The rule replacement API should not really be in cmLocalGenerator, but
it was historically, and this coupled many other things together here
too, such as output conversion. Make the output converter a parameter
so that rule replacement can be removed from cmLocalGenerator.
The same variables are replaced/retrieved from cmMakefile again and
again. Use a container so that they don't have to be retrieved
repeatedly, and to simplify the nested loop.
This one is not like the others as it doesn't participate in
substitutions. Keep ExpandRuleVariables doing only one thing and make
callers responsible for inserting a launcher prefix, simplifying the
code all-around.
Remove now-obsolete InsertRuleLauncher method.
Add a ConvertToOutputForExisting method which can be made virtual later
to satisfy different generator needs.
Pass additional strings as parameters for now. They can be turned into
class state later.
Add a cmOutputConverter to the cmLinkLineComputer and factory methods to
facilitate shell escapes.
Add state to the cmLinkLineComputer to record whether outputting for
response files or for watcom, to satisfy the cmOutputConverter API.
These are constant for the lifetime of the cmLinkLineComputer, even when
its functionality is extended in the future. This also keeps the
signatures of cmLinkLineComputer relatively simple.
Pass the cmComputeLinkInformation as a method parameter so that
cmLinkLineComputer is free from target-specific state. An instance
should be usable for all targets in a directory.
Remove the cmGeneratorTarget from the interface.
This is simplification of the OutputLinkLibraries responsibilities so
that it can be broken apart into multiple methods.
CMake has several classes which have too many responsibilities.
cmLocalGenerator is one of them. Start to extract the link line
computation. Create generator-specific implementations of the interface
to account for generator-specific behavior.
Unfortunately MSVC60 has different behavior to everything else and CMake
still generates makefiles for it. Isolate it with MSVC60-specific
names.
