FindKDE4
|
|
--------
|
|
|
|
|
|
|
|
Find KDE4 and provide all necessary variables and macros to compile
|
|
software for it. It looks for KDE 4 in the following directories in
|
|
the given order:
|
|
|
|
::
|
|
|
|
CMAKE_INSTALL_PREFIX
|
|
KDEDIRS
|
|
/opt/kde4
|
|
|
|
|
|
|
|
Please look in ``FindKDE4Internal.cmake`` and ``KDE4Macros.cmake`` for more
|
|
information. They are installed with the KDE 4 libraries in
|
|
$KDEDIRS/share/apps/cmake/modules/.
