In commit v3.11.0-rc1~433^2~1 (Add support for IMPORTED GLOBAL targets
to be aliased, 2017-09-14) we accidentally dropped the error on calling
`add_library` to alias an imported target that is not globally visible.
The `add_executable` command's equivalent check was properly updated.
Restore the check in `add_library` with the same update.  Also fix the
test case accordingly.

The change in commit v3.11.0-rc1~334^2 (FindOpenMP: Use NO_DEFAULT_PATH
where appropriate, 2017-11-15) broke partial support for Intel on Windows.
Since `OpenMP_${LANG}_IMPLICIT_LINK_DIRS` is empty for this compiler
the `find_library` call without `NO_DEFAULT_PATH` worked accidentally
in environments with the needed libraries in the search path already.

Fix support for Intel on Windows by simply removing our explicit search
for the `libiomp5md` library.  In cases that it is needed, the compiler
already inserts metadata in `.obj` files to tell the MSVC linker to use
the library.

Since commit v3.11.0-rc1~467^2 (VS,Xcode: Add CMakeLists.txt sources
without mutating targets, 2017-10-18) we do not add `CMakeLists.txt` to
target sources but instead generate references to them directly.  This
broke projects that explicitly specify their `CMakeLists.txt` file as a
source file because the explicit entry is no longer consolidated with
the generated one.

Teach the relevant generators to avoid duplicating `CMakeLists.txt`
source references and add test cases.

This reverts commit v3.11.0-rc1~108^2 (CheckIncludeFiles: Honor

affect checks in existing projects that don't expect the behavior.
Introducing the behavior again will require a policy.

This adds a dedicated mutex for file reading and writing to
cmQtAutoGenerator::FileSystem. The purpose of the change is
to avoid that long files reads block cmsys based path computations,
which are protected by an other mutex.

Refactoring in commit v3.9.0-rc1~156^2 (c++: prefer vectors over lists,
2017-05-04) switched `cmCTestSVN::Repositories` from `std::list` to
`std::vector`.  This can cause re-allocation when svn externals are
processed and break the `RootInfo` pointer that is supposed to point at
the first repository element.  Switch back to `std::list` so that the
address remains stable.

Revert commit v3.8.0-rc1~305^2 (Remove CTestTestfile.cmake when BUILD_TESTING
is OFF, 2016-11-14) again.  We reverted it once in commit v3.8.0-rc3~22^2
(Revert "Remove CTestTestfile.cmake when BUILD_TESTING is OFF", 2017-03-06) but
it was accidentally restored by commit v3.11.0-rc1~387^2 (server: add
"ctestInfo" request to get test info, 2017-10-25), perhaps due to conflict
resolution during rebase.

We cannot remove `CTestTestfile.cmake` when testing is off because it breaks
projects that never enable testing but create their own `CTestTestfile.cmake`
manually instead.  Revert the change again and add a test case.
