The GenerateExportHeaders test was failing on one machine, the version
could not be determined there, so the _gcc_version was empty,
so the first argument to if() was empty, so it complained:
http://open.cdash.org/testDetails.php?test=135623436&build=2016288
Use double quotes to turn the non-existant first argument into an empty
string.

Since we know which compiler we have we can test those OpenMP flags first that
are likely to be correct. This doesn't make any difference for GNU compilers,
but it should avoid useless try_compiles and output cluttering for all others.
For all current build machines the modules FindPkgConfig, FindFreetype, and
FindLibXslt return a version number. Enforce this to early catch when this
is not always the case.
This did not work because find_library() did only treat the given name as
complete filename if is matched "PREFIX.*SUFFIX":
find_library(MYLIB libfoo.so.2)
Now it is also taken as a whole if the name matches "PREFIX.*SUFFIX\..*".
Newer Ruby versions (from 1.9 onward) seem to warn if you query Config::CONFIG
and print a warning to use RbConfig instead. RbConfig seems to also work in
older versions, at least in 1.8. Use a macro to query RbConfig first and only
if that doesn't give anything fall back to Config.
"argument unused during compilation" -- well, thanks, but ...
If somebody has a fix to eliminate this warning entirely, rather
than simply suppressing it from our dashboard results, I'm all
ears.
Append a random number to the "cmTryCompileExec" file name to avoid
rapid creation and deletion of the same executable file name. Some
filesystems lock executable files when they are created and cause
subsequent try-compile tests to fail arbitrarily. Use a different
name each time to avoid conflict.
This contains a change, which changes the behaviour a bit:
now X11_xf86vmode_FOUND is only set to TRUE and the include directory
is added to X11_INCLUDE_DIR, if additionally to X11_xf86vmode_INCLUDE_PATH
also X11_Xxf86vm_LIB has been found.
I hope this doesn't cause regressions somewhere.

Configure the build_mingw.cmake.in config_mingw.cmake.in files
into the binary directory of the directory being built, not the
top level binary directory for the project.
Even if there are no lines covered in the file the gcov coverage report still
contains valueable information, the amount of uncovered lines and which exactly
they are. Set 'Covered="true"' for files we have a gcov report for even if they
have no lines covered. Otherwise CDash will neither show the uncovered line
count nor the detailed coverage report for this file.
When CTEST_EXTRA_COVERAGE_GLOB was used to collect otherwise uncovered files
'Covered="true"' was unconditionally set, so this can't be worse here.
This also cleans up a bunch of things on the way:
-when perl was queried for paths they were not converted to CMake style on
Windows.
-the result when perl was queried for the perl library name was ignored since
it was expanded with the possible paths, which is not a valid input for
find_library(). If perl returns a library name we now will look only for this
name and not for the default names and use the default names only when the
executable does not give us a hint.
-get rid of 2 variables that were only used at one place and directly put the
values in the call to find_library() and find_path().
