Hi Mike,
This only works during the CMake configure process, not during the
build. So it's possible for this information to be out of date. I
think I'll have to make a bogus target to grab the info from Subversion,
which is not what I had wanted to do.
You should just use a cmake -P script to create a header file or .cxx
file that has the information you want in it.
You would use a custom command to drive this.
You should be able to follow this FAQ entry:
http://www.vtk.org/Wiki/CMake_FAQ#How_do_I_generate_an_executable.2C_then_use_the_executable_to_generate_a_file.3F
So, something like this:
ADD_CUSTOM_COMMAND(
OUTPUT myVersion.cxx
COMMAND ${CMAKE_COMMAND} -P ${CMAKE_CURRENT_SOURCE_DIR}/version.cmake
DEPENDS generate ${CMAKE_CURRENT_SOURCE_DIR}/version.cmake
)
ADD_EXECUTABLE(product product.c myVersion.cxx)
version.cmake:
execute_process(svn ....)
configure_file(myVersion.cxx.in myVersion.cxx)
