I realized that converting libalkimit >= 5.0.0 to use QT4 is probably  
not as good a solution as I was thinking, as it would be a conversion,  
not an addition, so that version would still not be good for the  
frameworks version of KMM.

So, I figured I would installing 4.3.2 somewhere out of my main tree,  
and point cmake for 4.8 git heat to that version.  However, nothing I  
have tried has worked - it keeps finding the version of libalkimia from  
it's git head (under/usr) instead.  Oddly, it looks like CMakeLists.txt  
has a test and should fail for libalkimia >= 6.0.0 but it claims it  
finds 6.0.9 but is not failing.  Is this a cmake bug, or am I not  
understanding something?

I have tried setting CMAKE_PREFIX_DIR (and several variations) both as  
an environment variable and with -D, and I have tried setting  
LibAlkimia_DIR, but cmake is either ignoring them, or not finding what  
it wants.  Is perhaps part of the problem that prior to 5.0.0,  
libalkimia only produce a FindLibAlkimia.cmake and not and  
....Config.cmake?

For now, I will uninstall the more recent libalkimia from my main tree  
and install the older version, but I'd prefer to have all the  
frameworks related stuff in my main tree, and any remnant KDE4 stuff  
that cannot coexist installed elsewhere.  On that note, I don't know if  
it is inherent to the alkimia install or to the gentoo ebuild that the  
qt4/kde4 qt5/frameworks versions cannot be installed at the same time,  
since several of the files have identical names in both.

Am I just trying the impossible?
