Calling `project()` or `enable_language()` from a toolchain file will
infinitely recurse since those commands load the toolchain file.
Diagnose and reject this case with an error message instead of crashing
when the stack eventually overflows.
Although we fail with an error on a hash mismatch, it is not a fatal
error so the script may continue processing. If the download itself had
no error then report in the STATUS variable that the operation was not
successful due to the hash mismatch.

Add regression tests for the arguments handling in
cmake_parse_arguments. The tests were run also against cmake 3.4.1
maint branch to verify that there are no regressions.

Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use
of `add_library(... STATIC ...)` for the generated test project.
This will be useful for cross-compiling toolchains that cannot
link a binary without custom flags or scripts.
We use the host OS X version as the deployment target for this test.
This breaks if the SDKROOT environment variable specifies an
incompatible SDK version. Explicitly specify `macosx` as the
SDK so that CMake will automatically select a version matching
the deployment target.
This reverts commit 9beb2744d7.
Our AUTOMOC documentation states that it should be possible to
`#include "moc_foo.cpp"` in `foo.cpp`, and this will not work if
the file is placed in a different directory. Another solution
will need to be found to the original problem.

In commit v3.5.0-rc1~43^2 (Fix export of STATIC library PRIVATE
dependencies with CMP0022 NEW, 2016-01-15) we taught
target_link_libraries to generate `$<LINK_ONLY:$<TARGET_NAME:dep>>` in
INTERFACE_LINK_LIBRARIES instead of `$<LINK_ONLY:dep>` so that `dep` can
be recognized as a target name and updated during export. However, this
approach does not work when `dep` is just a plain library name and not a
target because `$<TARGET_NAME:...>` requires the name of a reachable
target.
Since we do not know during target_link_libraries whether the name will
correspond to a reachable target or not, we cannot inject the
`$<TARGET_NAME:...>` expression. Revert this change and solve the
original problem instead by teaching the export logic to recognize and
update target names directly in `$<LINK_ONLY:...>` expressions.

Check found libraries version to match user required version.
Protobuf compiler executable version is checked to be aligned with found
libraries, raising a warning message otherwise.
CPACK_* variables expect component name in upper case.
CPACK_RPM_* variables expected component name to be
in same case as component name.
This patch adds support for CPACK_RPM_* variables with
upper case component names to match the convention with
CPACK_* variables and also preserves same case component
names for back compatibility.
There's no need to stringify the values, but instead just pass in
strings. The core problem is that the path may have tokens which are
replaced by the preprocessor which causes an invalid path to be used.
The re-implementation in commit v3.5.0-rc1~116^2~1 (CMakeParseArguments:
replace by native cmake_parse_arguments command, 2015-12-05) introduced
a regression when parsing the ARGN arguments with cmake_parse_arguments.
The original implementation used
foreach(currentArg ${ARGN})
to iterate over input arguments. This flattened ;-lists within the
arguments whether they were quoted or not. Fix our new implementation
to preserve this behavior and add a test case to cover it.

a1ad098d Tests: Avoid OS X 10.5 limitation warning in RunCMake.install test
47460f3e install(EXPORT): Fix crash on target in another directory
e86383e1 Tests: Use newer policy settings in RunCMake.install test
The EXPORT-OldIFace test case uses install(TARGETS) and so generates a
warning:
CMake Warning in CMakeLists.txt:
WARNING: Target "foo" has runtime paths which cannot be changed during
install. To change runtime paths, OS X version 10.6 or newer is required.
Therefore, runtime paths will not be changed when installing.
CMAKE_BUILD_WITH_INSTALL_RPATH may be used to work around this limitation.
Set CMAKE_BUILD_WITH_INSTALL_RPATH to avoid the warning since we do not
need to run the binaries from the build tree anyway.
Previously we did not clearly document that `--target` is only supported
to be specified once. Even worse, specifying it multiple times would
silently ignore any previously specified targets and only build the last
target.
Update the documentation to specify this. Update the implementation to
reject multiple `--target` options to prevent user errors.
Updates to Tests/Fortran by commit v3.2.0-rc1~501^2 (Avoid if() quoted
auto-dereference, 2014-10-14) changed our check
"${CMAKE_Fortran_COMPILER_ID}" MATCHES "${CMAKE_C_COMPILER_ID}"
to
CMAKE_Fortran_COMPILER_ID MATCHES CMAKE_C_COMPILER_ID
because CMP0054 warned about the LHS compiler id "MSVC" being expanded.
However, the RHS of if(MATCHES) does not auto-dereference so this check
has returned FALSE since then and the FortranCInterface part of the test
has not been running!
Fix this by using STREQUAL with quoted arguments and setting CMP0054 to
NEW (by requiring 3.1).
Refactoring merged by commit v3.5.0-rc1~299 (Merge topic
'use-generator-target', 2015-10-20) in and around
commit v3.5.0-rc1~299^2~13 (cmExportSet: Store a cmGeneratorTarget,
2015-10-17) changed export sets to delay looking up actual targets and
stores only their names. However, in InstallCommand::HandleExportMode
we need to lookup targets immediately to check them for
EXPORT_LINK_INTERFACE_LIBRARIES. The check was accidentally made local
to the current directory, so if an export set contains a target from
another directory the lookup fails and CMake crashes. Fix the check to
look up the target name globally, and tolerate when no target is found
just in case.

Refactoring in commit v3.5.0-rc1~347^2~2 (Set the current dirs on the
snapshot before creating the cmMakefile) accidentally changed the
source and binary directories configured in `cmake -E cmake_depends`
for use during dependency scanning. This can cause the wrong directory
information to be loaded. It also breaks Fortran module dependency
scanning for modules provided by targets in subdirectories that do
not have Fortran_MODULE_DIRECTORY set.
Fix the dependency scanning directory configuration and add a test to
cover the Fortran module case in which the breakage was observed.

While evaluating `if(MATCHES)` we get a `const char*` pointer to the
string to be matched. On code like
if(CMAKE_MATCH_COUNT MATCHES "Y")
the string to be matched may be owned by our own result variables.
We must move the value to our own buffer before clearing them.
Otherwise we risk reading freed storage.
The add_custom_command(TARGET) signature only works for targets defined
in the current directory. Clarify this in the error message when the
target exists but was defined elsewhere.

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.
