+The following options are recognized when passed to cmake:
 
- -config debug        Create a debug build
- -config release      Create a release build
-		      The default depends on how Qt was built.
- V=1                  Disable the "silent" build mode
- LIBDCDEVEL=1         Search for libdivecomputer in ../libdivecomputer
- LIBMARBLEDEVEL=path  Search for marble library and includes in path
- SPECIAL_MARBLE_PREFIX=1 Use libssrfmarblewidget as library name
-                      This is needed when building with our marble branch
- LIBGIT2DEVEL=path    Search for libgit2 library and includes in path
- INCLUDEPATH+=xxx     Add xxx to the include paths to the compiler
-		      (pass the actual path, without -I)
- LIBS+=xxx            Add xxx to the linker flags. -l and -L options are
-		      recognized.
- DEFINES+=SHOW_PLOT_INFO_TABLE=1
-		      Only available in debug builds, this creates a
-		      second window that shows all elements in the
-		      plot_info structure as a table - very useful when
-		      debugging issues with the profile
+ -DCMAKE_BUILD_TYPE=Release	create a release build
+ -DCMAKE_BUILD_TYPE=Debug	create a debug build
 
-The INCLUDEPATH and LIBS options are useful to tell the buildsystem
-about non-standard installation paths for the dependencies (such as
-Marble). They can be repeated as often as needed, or multiple
-arguments can be passed on the same switch, separated by a space. For
-example:
-
-  qmake LIBS+="-L$HOME/marble/lib -L$HOME/libdivecomputer/lib" \
-	INCLUDEPATH+="$HOME/marble/include $HOME/libdivecomputer/include"
+The Makefile that was created using cmake can be forced into a much more
+verbose mode by calling
 
+ make VERBOSE=1
