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 ${FREETYPE_INCLUDE_DIRS}
If the GTK_XXX_LIBRARY_DEBUG library is available, it is now used when
linking in debug mode XXX.
A new set of variables GTK_XXX_LIBRARY_RELEASE is added and the
original GTK_XXX_LIBRARY uses the optimized/debug syntax.
Before this, when creating GTK2_LIBRARIES, FindGTK2 added the GTK
dependencies in wrong order into GTK2_LIBRARIES. With dynamic libraries
this is not a major problem, but when linking to static gtk libraries,
the linker outputs a lot of undefined symbols. Reorder the calls that
append libraries to GTK2_LIBRARIES to respect dependency order.
The changes in "use PATH_SUFFIXES to simplify find_* calls" on 8/14
regressed important functionality in FindGTK for using find_path to
locate header files in <prefix>/lib/<gtk_package>/include.
The find_path function doesn't search <prefix>/lib only <prefix>/include.
Instead of reading the whole file using file(READ) and later matching on the
whole file use file(STRINGS ... REGEX) to get only those lines we are
interested in at all. This will make the list much smaller (good for debugging)
and also the regular expressions will need to match on much smaller strings.
Also unset the content variables once they are not used anymore.
Especially remove "lib64" when the given paths are all Unix ones and "lib" is
also explicitely given. In that case CMake will search "lib64" anyway for
platforms where it is known to make sense.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
