QT4_CREATE_MOC_COMMAND is given a moc_flags argument that contains the
COMPILE_DEFINITIONS and a potentially large list of include directories.
Since it is a macro, the ${moc_flags} reference is replaced with this
content and sent through cmMakefile::ExpandVariablesInString (EVIS).
Since commit v3.0.0-rc1~138^2 (Qt4: Use generator expression in
COMPILE_DEFINITIONS, 2014-01-13) the COMPILE_DEFINITIONS value contains
a '$' so the EVIS fast-path is no longer used. Instead the full
cmCommandArgumentParserHelper is now used on the large input, which is
very slow (since it was originally created for hand-written code).
Change QT4_CREATE_MOC_COMMAND to a function instead of a macro to avoid
passing large content through EVIS. This makes it significantly faster.
Restore support for the undocumented <CONFIG>_LOCATION target property
removed by commit v3.0.0-rc1~175^2 (cmTarget: Remove support for
<CONFIG>_LOCATION property, 2013-12-30) as part of the CMP0026 OLD
behavior.
Override the QT_QTMAIN_LIBRARY cache variable with a regular
variable in the Qt 5 configuration. This avoids linking with the
Qt 4 version of the WinMain library.
According to the Intel release notes:
http://software.intel.com/sites/default/files/l-compiler-release-update.pdf
the __INTEL_COMPILER_UPDATE predefined macro was introduced to hold the
third version component.

Test the first argument directly for matching 'EXACT'. The error
check in its previous position was incorrect and would only trigger
with a version of '0' or similar.
During cross-compiling the toolchain file may use CMakeForceCompiler to
force a compiler setting. When using the Xcode generator try to convert
it to a full path by searching the PATH as is done for the Makefile
generators.
Visual Studio is handled as a special case for autogen depends. However,
the special handling works only for target dependencies, not file
dependencies output by a custom command.
Use a PRE_BUILD step only if all depends are targets.
Commit v3.0.0-rc1~71^2~9 (Qt4: Use IMPORTED executable names with
custom commands., 2014-01-24) erroneusly changed this command to
use the wrong target.
If a package is requested with an EXACT version, that doesn't imply
that dependencies must be found EXACTly too.
Extend the macro to allow specifying that a dependency must be found
by EXACT version instead.
Recently used cmake-gui locations are searched only on Windows because
the Windows registry is used to record the values. This behavior is
historical and may be removed by a policy in the future so rather than
implementing it on other platforms simply document the current behavior.
This command does not support generator expressions. The documentation
was mistakenly extended to claim it in commit v3.0.0-rc1~60^2~3 (Help: Mark
up the buildsystem commands documentation, 2014-02-03).
