Prior to the existence of the if(DEFINED) condition, many of our Check
modules implemented the condition with a hack that takes advantage of
the auto-dereference behavior of the if() command to detect if a
variable is defined. The hack has the form:
if("${VAR} MATCHES "^${VAR}$")
where "${VAR}" is a macro argument reference. However, this does not
work when the variable named in the macro argument contains characters
that have special meaning in regular expressions, such as '+'. Run the
command
git grep -E 'if\("\$\{.*\}" MATCHES "\^\$\{.*\}\$"\)' -- Modules/Check*
to identify lines with this problem. Use if(NOT DEFINED) instead.
In commit v3.0.0-rc1~551^2~1 (Check*CompilerFlag: make C and CXX modules
share most error patterns, 2013-08-08) a pattern containing a ';' was
moved out of a ""-quoted argument and into a variable. CMake flattens
the containing list and breaks the pattern. Use a '.' to match ';'.
Also fix .bz2 extension to be .tar.bz2 since we only support compressed
tarballs and not plain compressed files.

7079f33d WindowsCE: Drop unused Platform/WindowsCE-MSVC module
05373f7e WindowsCE: Refactor setting of "WINCE"
1acde6b0 MSVC: Use STREQUAL to check for WindowsCE
This module was created to mirror Platform/Windows-MSVC.cmake, but this
is not necessary because nothing includes "Platform/<os>-<id>.cmake"
directly. The Platform/Windows-MSVC module is only a helper for the
Platform/Windows-MSVC-<lang> modules.
Move it to the Platform/Windows module since it is independent of the
compiler used. While at it, remove redundant "WIN32" setting from
Platform/Windows-MSVC since Plaform/Windows already sets its.

If find_program does not find CMAKE_<LANG>_COMPILER, use set_property()
to force the value to be that of CMAKE_<LANG>_COMPILER_INIT instead of
set(). This allows us to set the value without re-specifying the type
and documentation, thus preserving what find_program set.
Commit v3.0.0-rc1~111^2 (QNX: Introduce QCC compiler id for that
QNX platform compiler., 2014-01-20) split handling of the QNX QCC
compiler into a separate compiler-id. That refactoring results in
the QCC compiler not using the CMake-compiler-id "GNU", which means
that the __compiler_gnu macro is no longer executed for it.
Add Compiler/QCC*.cmake modules to define and call the __compiler_qcc
macro and teach it to call __compiler_gnu internally. Remove the
corresponding pieces from the Platform/QNX*.cmake modules.
It is also necessary to change the language conditional to dereference
the lang macro parameter, which is another bug introduced by the
same commit. The extra -lang-c++ flag is only necessary when the CXX
compiler is specified as 'qcc' instead of 'QCC' in the toolchain file,
which is why this bug was not noticed before. The flag is also necessary
in that case when linking in order to find the appropriate standard
libraries. The flag was not previously added when linking executables,
so linking failed even with CMake 2.8.12 with the lower-case compiler-id.

Before this commit, you would have to run ctest -S mode to get
MemoryCheckType to work. This is because CMAKE_COMMAND was not set.
The fix is to use cmSystemTools::GetCMakeCommand instead.
Produce a more consistent result by finding only a single include
directory and reporting which headers may be included from it. The
previous search for each header separately might find pieces from
separate and incompatible packages.
While at it, provide the CURSES_INCLUDE_DIRS result variable to be
consistent with other modules.
On WinCE we must link both shared libraries and executables with the
/subsystem:windowsce flag. Teach Platform/Windows-MSVC to pass it
to the linker in both cases.
