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.
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.

Move all development release notes into a new version-specific document:
tail -q -n +3 Help/release/dev/* > Help/release/3.5.rst
git rm -- Help/release/dev/*
except the sample topic:
git checkout HEAD -- Help/release/dev/0-sample-topic.rst
Reference the new document from the release notes index document.
Add a title and intro sentence to the new document by hand.
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.
