Bug 342477

Trying to compile libkdepim without Baloo, the compilation failed due to hard dependency on it. However, cmake reported Baloo as an optional component.

The respective CMakeLists reads 'TYPE REQUIRED' but the output is

...
-- The following OPTIONAL packages have not been found:

 * Baloo (required version >= 4.14.0) , The Baloo libraries , <http://www.kde.org>
   Baloo provides search capabilities in KMail and Akonadi
...

This has been discussed in bug 342015 and it was suggested in comment #3 to file the particular issue about wrong cmake output as a kdelibs bug, so here it is.

Reproducible: Always

Steps to Reproduce:
1. install kdepim build dependencies but not Baloo
2. unpack kdepim-4.14.3.tar.xz
3. cmake .

Actual Results:

Well, note that in fact I'd rather expected that Baloo is _really optional_, but since it isn't, see the bug 342015, it should not be reported as such ...

my kdelibs version is 4.14.3 (cannot be selected from the list in the Version field, hence 'unspecified')
