Re: [CMake] This has to have been asked before...
It is presently not possible to iterate over all the targets in
CMakeLists.txt unless you maintain your own list of targets. It would be a
good feature request to provide the full list of CMake targets using:
get_cmake_property(var TARGETS) # for all
targets from top level all the way down
or
get_property(var GLOBAL CMAKE_TARGETS ... # for all targets from
top level all the way down
or
get_property(var DIRECTORY CMAKE_TARGETS ... # for targets just in the
current directory
However, presently, nothing like this is implemented. Wouldn't be too hard,
just hasn't been done yet.
HTH,
David

Well, thanks for trying, but what I actually want to know is how to add
something to all the current targets *automatically* - as in without
specifying them by hand, and how to get the compiler flags etc of a
particular target so that I can *generate* a custom command that matches
the given target.
get_file_component(pchbase ${PrecompiledHeader} NAME_WE)
get_file_component(pchpath ${PrecompiledHeader} PATH)
*foreach ( target in LISTS CMAKE_TARGET_LIST )*
set(pchname ${CMAKE_BINARY_DIR}/${pchbase}.${target}.h)
get_target_properties(defines ${target} COMPILE_DEFINITIONS)
get_target_properties(flags ${target} COMPILE_FLAGS)
set_target_properties(${target} PROPERTIES COMPILE_FLAGS ${flags}
-include ${pchname} -Winvalid-pch)
add_custom_command(${target} PRE_BUILD COMMAND
ln -s ${pchname} ${PrecompiledHeader}
g++ ${defines} ${flags} -o ${pchname}.gch ${pchname})
)
endforeach ()
Marked in bold is the part I'm struggling with.

Re: [CMake] This has to have been asked before...
What I did is define custom functions that wrap add_executable, add_library and
target_link_libraries. Works like a charm ;-)

[CMake] This has to have been asked before...
I'm probably not using the right keywords on my search. I want to add a target (a gcc precompiled header) as a dependency for every target so it'll get compiled with the flags for that particular target, including altering the resulting file name. I did try looking at the precompiled header CMake include, but that just confused the bejeezus out of me, not helped by the fact that it didn't work :) - Oliver ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
