81ecc726 FindCUDA: Added some additional comments about non-existent dependency files.
4b561b4c FindCUDA: Fix for when a non-existent dependency file is found.
Due to #4662 -isystem support was disabled for all GNU Compilers
on Apple platforms. But the change was probably a just work around
for a broken compiler on Tiger (see 10837#c27206). So we tighten
the condition to only kick in for GCC versions earlier than 4.
That should ensure sane behavior for Xcode 3.2 and later.
Previously if a non-existent dependency file is found we set the file to "" and
then do if(NOT IS_DIRECTORY "${file}"). Later we call get_filename_component
on the empty file which returns basically the current build directory.
Having a dependency on the current build directory is really annoying, because
anything that compiles into that directory will change the file stamp and
cause your files to rebuild every time you call make. :(
Since commit v3.5.0-rc1~32^2~1 (ExternalProject: Simplify `cmake
--build` configuration passing, 2016-01-19) we use the `$<CONFIG>`
generator expression to generate the `cmake --build . --config <config>`
value for the default BUILD_COMMAND instead of the CMAKE_CFG_INTDIR
placeholder value provided by multi-config generators. However, some
projects have been abusing the old implementation detail by setting
CMAKE_CFG_INTDIR themselves to get a specific configuration. Those
projects should be updated to set their own BUILD_COMMAND to get
non-default behavior. Meanwhile we can be compatible with their
existing releases by detecting when CMAKE_CFG_INTDIR is not a
generator-provided placeholder and using its value instead.
The dependency flags require recent versions of `iccarm` and `iccavr`.
The multi-rule dependency generated with `--dependencies=m` does not
work well with Ninja, so use `--dependencies=ns` instead.
Imported targets are now the recommended way of dealing with external
library dependencies. Add one for FindPNG and update documentation
accordingly. Also add a test case activated by CMake_TEST_FindPNG.
Check CMAKE_CONFIGURATION_TYPES instead of CMAKE_CFG_INTDIR in order
to recognize multi-config generators. Then use $<CONFIG> to pass
the configuration value.
The original value is saved in `_pkg_config_path_old`. Fix this typo
left by commit v3.1.0-rc1~763^2 (FindPkgConfig: Extend PKG_CONFIG_PATH
using CMake variables, 2014-03-06).
In Modules/Platform/WindowsPaths.cmake our previously recorded
environment variable combinations no longer seem to be correct. For
example, a 64-bit cmake binary may see ProgramW6432 in the environment
and end up not considering the "ProgramFiles(x86)" variable. Instead
check for all possible environment variables in the preferred order and
then remove duplicates.

Add `VERBATIM` to all `add_custom_command` calls so that CMake will
escape arguments properly even when special characters such as "()" are
present.

Most packages install their .pc files into PREFIX/lib/pkgconfig, but
some put them into PREFIX/share/pkgconfig. Either is valid, and
pkg-config itself looks in both for the /usr and /usr/local prefixes.
This fixes an issue where some packages (yajl, for example) are not
found if they are installed into a non-standard prefix and
CMAKE_PREFIX_PATH is used to locate them.
This improvement to the FindDCMTK module improves compatibility with recent
DCMTK, which provides a DCMTKConfig.cmake file. See the module comments for a
compatibility matrix.
It also provides DCMTK_INCLUDE_DIRS.

This was added by commit v2.8.0~2292 (... Set variable
wxWidgets_INCLUDE_DIRS_NO_SYSTEM on the Mac ..., 2008-04-16) and updated
by commit v2.8.9~183^2 (FindwxWidgets: Do not use -isystem on OpenBSD,
2012-05-14). Since the underlying cause was never investigated fully we
do not know the conditions under which -isystem breaks wxWidgets, but
suppressing -isystem is problematic for users that do not want to see
warnings in wxWidgets headers. Simply drop the special case for now so
we can see whether anyone hits the problem again, at which point it can
be investigated in more detail.

Drop the 'UNIX' condition on Clang compiler features. This enables
use of compile features with MinGW Clang, though additional work may
be needed for clang-cl.
