Zitat von Marc Schafer <[email protected]>:
I have a java program that generates a header file for the C++ shared
library that I am trying to build with cmake. The java generator has an ant
script that runs it but it does not take a destination directory for an
argument. Therefore I have to run it and then copy the resulting files into
my binary directory. I created the following custom target to do this:
I suggest to do it diffently: copy the source with copy_if_different
into your build tree and create the .h file there.
If the source files are mentioned in the .xml file, you can use
configure_file() to create the .xml (in build tree) from an .xml.in
file (in source tree) and run ant on the result.
add_custom_target ( generated_messages ALL
COMMAND
${ANT_EXECUTABLE} -f ${PROJECT_SOURCE_DIR}/java/MessageGenerator/build.xml
run
COMMAND
${CMAKE_COMMAND} -E copy_if_different ${DICTIONARY_DIR}/c/messages.h
${PROJECT_BINARY_DIR}/include/messages.h
)
Make that a add_custom_command() to get the dependencies right. The
custom command for the .h file should have the .xml as dependency (see
above).
