This function avoids creating the targets when the required
dependencies were not found.
Also fix some wrong dependency and some typo.
${FREETYPE_INCLUDE_DIR_ft2build} ${FREETYPE_INCLUDE_DIR_freetype2} are
now required for gtkmm component
Some libraries (e.g. gio) are not necessary, and often not available
with older GTK2 versions, therefore GTK_LIBRARIES should not contain
GTK2_XXX-NOT_FOUND for these libraries.
As discussed on the mailing list, freetype includes used in GTK2
headers libraries do not require to link the library explicitly (even
though it is already linked by GTK2 libraries.
Also remove _GTK2_ADD_TARGET_LIBRARIES no longer used and use
${FREETYPE_INCLUDE_DIR_ft2build} ${FREETYPE_INCLUDE_DIR_freetype2}
variables instead of ${FREETYPE_INCLUDE_DIRS}
Also add a comment explaining the purpose of the include/SDL* path
suffixes. As explained in commit 7cb51739 (FindSDL: Restore
accidentally dropped search paths (#13651), 2012-11-05) the include/SDL*
path suffixes are for looking in the ENV{SDLDIR} location.

* Haiku does not define __BEOS__ anymore, so there is no need to guard
these BeOS specific workaround for Haiku.
* The workaround themselves are not needed for Haiku as it has much
better POSIX compatibility than BeOS did.

* Do not define BEOS anymore (this includes workarounds which we don't
need most of the time in Haiku, so we prefer opt-in IF(HAIKU) in the
cmake files instead).
* On the other hand, do define UNIX (we are trying to be compliant) and
HAIKU (there is still a number of things we don't do like the
average UNIX clone)
* Do not use UnixPaths, as our filesystem hierarchy isn't anything like
what it expects.
* Do not use -nostart, which the compiler doesn't know about anymore.
This used to be an Haiku extension to gcc, and is equivalent to
-shared which is the default gcc option.
* While "dl" functions are provided in libroot, this is always
implicitly linked so there is no need to tell cmake about it.
* Forcing position-independent code is not needed, so remove it.
* On the other hand, include appropriate linker options for executables
and shared libraries.
* Support for the two available compilers in Haiku (gcc2 and gcc4) and
pick the right headers and libraries according to the currently
selected one.
* With the adoption of the package manager, the directory layout was
changed. Tell cmake where to look for header files and libraries.
* As we don't define BEOS anymore, enable the workaround we still need
for HAIKU as well. This is the lack of a libm (it is part of the
implicitly linked in libroot)

Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, the result variable would be set to
false, even if the struct has that particular member.
Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use. The new
signature is therefore:
CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable>
[LANGUAGE <language>])
This assumes that coverage.py has been run in such a way to produce its
standard XML output. This uses the Cobertura schema and should be somewhat
generalizable.
Add a new command line argument to ctest. This allows users to
rerun tests that failed during the previous call to ctest. This
is accomplished by analyzing the most recently modified file named
"^LastTestsFailed*" in the Testing/Temporary subdirectory of the
project's binary directory.
Add an unset() command option to remove a variable from the calling
scope, just like the set() command's PARENT_SCOPE option. Teach the
Unset test to cover such cases.
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id. Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.
Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.
