When x11/grantlee and x11/grantlee-qt5 are installed at the same time,
kdevelop5 includes ${LOCALBASE}/include/grantlee and not
${LOCALBASE}/include/grantlee5 but links against grantlee-qt5. What obviously
doesn't work!
So move header files and cmake from grantlee into grantlee4. Just like
grantlee-qt5 does with grantlee5. All Qt4/KDE4 consumers are fine with
grantlee4.
Spotted by naddy@ in a amd64 bulk and sthen@ in a i386 bulk. Thanks for the
helpful reports!
