This is to permit VS2017 to make use of the vc141 suffix or
fall back to the compatible vc140 to use Boost libraries built
with VS2015.
Cherry picked from commit 3ca6f70f8b27c08ad3470542705701e6e8e6ea05
plus a fixup from commit 6115875bf0faef61c558e46395e67bdfd4ad48e1
for backport to CMake 3.8.
Since commit v3.8.0-rc1~136^2 (FindBoost: Search official location of
prebuilt binaries on Windows, 2016-12-21) we pass input paths through
`_Boost_UPDATE_WINDOWS_LIBRARY_SEARCH_DIRS_WITH_PREBUILT_PATHS` in more
places than before. This broke tolerance of backslashes in paths
provided by the user due to the macro argument re-parsing. Turn
`_Boost_UPDATE_WINDOWS_LIBRARY_SEARCH_DIRS_WITH_PREBUILT_PATHS` into a
function instead of macro to avoid re-parsing of macro arguments.
Fixes: #16816
These were added by commit v3.8.0-rc4~4^2~1 (RC: Add missing
CMAKE_RC_FLAGS_<CONFIG> entries to cache, 2017-03-28) and should be
advanced as they are for other languages.
Changes:
- Fix install script template (*.qs.in) to register on all platforms;
- Add patch version numter to display name ("CMake X.Y" -> "CMake X.Y.Z").
Latest wxWidgets git master version and the upcoming 3.1.1 release requires
linking with shlwapi and version DLLs. As this does no harm when using the
previous versions, just do it unconditionally.
The `ld` tool in Xcode 8.3 now has a `-lto_library <path>` flag. Ignore
the flag instead of accidentally parsing it as `-l` with `to_library`.
Fixes: #16766
Intel 17.0.2 on UNIX introduced a regression from 17.0.1 in its
definition of `__cpp_constexpr` in `-std=c++14` mode. It incorrectly
defines it as `200704` instead of the expected `201304`. Fix our
feature detection table to account for this.
If `CTestTestParallel` was run at the same time as `CTestTestChecksum`
(e.g. during parallel testing) then the former fails due to the latter
stepping on its directory. Fix the directory used for the latter to
avoid the conflict.
The change in commit v3.8.0-rc2~7^2 (ExternalProject: Run `git
checkout` with `--` to clarify arguments, 2017-02-24) broke the case of
`GIT_TAG some-remote-branch` because an explicit `--` means that the
preceding argument is a tree-ish instead of a branch. Revert the change
and leave a comment.
Fixes: #16763
The sdcc compiler no longer defines the `SDCC` preprocessor macro.
Instead `__SDCC_VERSION_MAJOR` and similar component-wise macros are
defined. Use them instead if defined.
Issue: #16746
In commit v3.8.0-rc1~304^2 (MSVC: Do not define _DEBUG explicitly when
using /MDd, 2016-11-15) we removed the `_DEBUG` preprocessor definition
from MSVC C and C++ flags because the `cl` compiler automatically
defines it in Debug builds anyway. However, the VS generators propagate
C preprocessor definitions to the RC (Windows Resource Compiler) tool.
This means that we used to explicitly define `_DEBUG` for RC debug
builds. Therefore existing project code may expect the definition to be
there even though the `rc` compiler itself does not implicitly define
`_DEBUG` in debug builds.
Add the `_DEBUG` flag to the default `CMAKE_RC_FLAGS_DEBUG` instead
to restore this definition for RC debug builds. This also makes it
available consistently in VS, Ninja, and Makefile generators.
Fixes: #16745
The VS generators use the C (or CXX) preprocessor definitions for
the Windows Resource Compiler tool. This causes definitions parsed
out of `CMAKE_RC_FLAGS[_<CONFIG>]` variables to be dropped. Fix
the implementation to preserve both.
Issue: #16745
The `sysconf(3)` manual explains that the return value can be `-1` for
limits if there is no definite limit. Recognize this case and skip
using the value as a limit candidate. Otherwise we use response files
unconditionally on such systems instead of checking other limits.
Fixes: #16740
Use our undocumented `cmake_host_system_information` query to find the
VS 2017 installation directory by asking the VS installer tool. Then
look relative to that for the redist directory.
Fixes: #16737
Add a query to the `cmake_host_system_information` command to get
the location of a VS 2017 installation. Leave it undocumented and
for internal use for now.
