I all CMakers,
We use doxygen to generated API documentation.
We have an ADD_CUSTOM_TARGET(apidoc ...) which runs doxygen.
I want to include generated documentation in the CPack
generated binary tarball/zip/... but:
1) I don't want doxygen to be run everytime we build
so I don't ADD_CUSTOM_TARGET(apidoc ALL ...)
but I wanted to force CMake to run through apidoc TARGET
when "make package" is called.
I tried to
ADD_DEPENDENCIES(package apidoc) but CMake
complains about non-existent "package" target.
For now I should remember to do a properly ordered:
make apidoc
make package
if I want the up-to-date generated documentation to be included
in the generated package.
2) The apidoc target is "generating" files I want to be "installed"
when calling
make install
The problem is my CMakeList.txt looks something like:
SET(APIDOC_DIR ${CMAKE_BINARY_DIR}/doc/api CACHE PATH "API
documentation directory")
ADD_CUSTOM_TARGET(apidoc
COMMAND ${CMAKE_COMMAND} -E echo_append "Building API Documentation..."
COMMAND ${DOXYGEN_EXECUTABLE} ${DOXYGEN_INPUT}
COMMAND ${CMAKE_COMMAND} -E echo "Done."
WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
)
FILE(GLOB_RECURSE doc_files RELATIVE ${APIDOC_DIR} ${APIDOC_DIR}/*)
FOREACH(file ${doc_files})
GET_FILENAME_COMPONENT(file_prefix ${file} PATH)
INSTALL(FILES ${APIDOC_DIR}/${file}
DESTINATION doc/${file_prefix})
ENDFOREACH(file)
Then I must run cmake twice for make install to work as I want.
More precisely I should do:
cmake
make apidoc
cmake
make package
My final question is:
How to get "build-time" generated file be properly intalled
and packaged with CMake/CPack?
