Hello,
I'd like to create a custom doxygen target for a project. The relevant parts
look like that:
/
doc/Doxyfile.in
lib/[files with all the documentation]
build/
CMakeLists.txt
Now what I'd like to have is a doxygen target where I can do something like
this:
$ cd build
$ cmake ../
$ make api-docs
I found some clues on this list and got this far:
INCLUDE( ${CMAKE_ROOT}/Modules/FindDoxygen.cmake)
CONFIGURE_FILE(${MYPROJECT_SOURCE_DIR}/doc/Doxyfile.in
${MYPROJECT_BINARY_DIR}/api-docs/Doxyfile
@ONLY IMMEDIATE)
ADD_CUSTOM_TARGET(api-docs ALL ${DOXYGEN}
\"${MYPROJECT_BINARY_DIR}/api-docs/Doxyfile\" )
I included this into ./CMakeLists.txt and it works well: The only problem is:
it is always executed when I do make. "make api-docs" does not work, so I
tried it that way:
ADD_CUSTOM_COMMAND(OUTPUT api-docs COMMAND doxygen)
IF (COMMAND doxygen)
INCLUDE( ${CMAKE_ROOT}/Modules/FindDoxygen.cmake)
CONFIGURE_FILE(${MYPROJECT_SOURCE_DIR}/doc/Doxyfile.in
${MYPROJECT_BINARY_DIR}/api-docs/Doxyfile
@ONLY IMMEDIATE)
ADD_CUSTOM_TARGET(api-docs ALL ${DOXYGEN}
\"${MYPROJECT_BINARY_DIR}/api-docs/Doxyfile\" )
ENDIF (COMMAND doxygen)
Try something like this:
add_custom_target (api-docs doxygen ${PROJ_SOURCE_DIR}/proj.doxyfile
WORKING_DIRECTORY ${PROJ_SOURCE_DIR} COMMENT "Generating documentation")
However, this doesn't work either. So the basic question is: How can I specify
a target for "make <target>" and do something in the CMakeLists.txt only when
that target is given? I don't want doxygen to run every time. Only when I say
so.
I suppose I fail to understand the "command" and "target" mechanism. What
would be an appropriate way to do this.
Thanks and Greetings...
Stephan
