Building individual libraries with cmake

help

In a configured cmake workspace, make help will display a list of available targets. Example:

% make help 
The following are some of the valid targets for this Makefile:
... all (the default if no target is provided)
... clean
... depend
... edit_cache
... install
... install/local
... install/strip
... list_install_components
... package
... package_source
... rebuild_cache
... boost_date_time
... boost_date_time-mt-shared
... boost_date_time-mt-shared-debug
... boost_date_time-mt-static
... boost_date_time-mt-static-debug
... boost_date_time-shared
... boost_date_time-shared-debug
... boost_date_time-static
... boost_date_time-static-debug
... boost_filesystem
... boost_filesystem-mt-shared
... boost_filesystem-mt-shared-debug
... boost_filesystem-mt-static
... boost_filesystem-mt-static-debug
... boost_filesystem-shared
... boost_filesystem-shared-debug
... boost_filesystem-static
... boost_filesystem-static-debug
[etc]

You can build any target by passing it as an argument:

% make boost_signals-static
[  0%] Building CXX object libs/signals/src/CMakeFiles/boost_signals-static.dir/trackable.cpp.o
[  0%] Building CXX object libs/signals/src/CMakeFiles/boost_signals-static.dir/connection.cpp.o
[100%] Building CXX object libs/signals/src/CMakeFiles/boost_signals-static.dir/named_slot_map.cpp.o
[100%] Building CXX object libs/signals/src/CMakeFiles/boost_signals-static.dir/signal_base.cpp.o
[100%] Building CXX object libs/signals/src/CMakeFiles/boost_signals-static.dir/slot.cpp.o
Linking CXX static library ../../../lib/libboost_signals-gcc41-1_35.a
[100%] Built target boost_signals-static

Preprocessing

In build directories corresponding to a source library containing a CMakeLists.txt containing a boost_add_library invocation (e.g. build/libs/signals/src, build/libs/filesystem/src), more detailed targets are available:

% cd libs/signals/src
% make help
The following are some of the valid targets for this Makefile:
  [many omitted]
... signal_base.o
... signal_base.i
... signal_base.s
... slot.o
... slot.i
... slot.s

making slot.i will run slot.cpp through the preprocessor:

% make slot.i
Preprocessing CXX source to CMakeFiles/boost_signals-mt-shared.dir/slot.cpp.i

If you are always interested in seeing the compiler flags you can enable CMAKE_VERBOSE_MAKEFILES via ccmake , or for a one-off just pass VERBOSE=1 on the command line:

% make VERBOSE=1 slot.i
make[1]: Entering directory `/home/troy/Projects/boost/branches/CMake/Boost_1_35_0-build'
