问题
tl;dr version: is it possible with CMake (>= 2.8) to generate zip files from some files and put the packed zip file in a specific location?
longer version: I have a CMakeLists.txt that build my project to a .exe file. And this exe file will read data from a zip file. Now it is so that the content to be packed in the zip file is in my git repository so that it can be edited, too. But the program needs this data in a zip file. So it would be good if the cmake script could take the data, put it in a zip file and place it next to the exe. I already heard of CPack, but I did not found easy examples and am not sure if this is even the right tool for my task.
Is this possible? If yes: how?
回答1:
Since version 3.2 CMake has the functionality to generate a zip file built-in. The CMake command-line mode sub-command tar
supports both the creation of zip and 7zip archives.
For example, if the current CMake source directory contains the file testfile.txt
and the directory testdir
, you can use the following CMake commands to create a zip file containing both items:
add_custom_target(create_zip COMMAND
${CMAKE_COMMAND} -E tar "cfv" "archive.zip" --format=zip
"${CMAKE_CURRENT_SOURCE_DIR}/testfile.txt"
"${CMAKE_CURRENT_SOURCE_DIR}/testdir")
As a work-around for earlier CMake versions, you can use the jar command that is part of a standard Java JRE installation.
find_package(Java)
execute_process(
COMMAND
"${Java_JAR_EXECUTABLE}" "cfM" "archive.zip"
"-C" "${CMAKE_CURRENT_SOURCE_DIR}" "testfile.txt"
"-C" "${CMAKE_CURRENT_SOURCE_DIR}" "testdir"
RESULT_VARIABLE _result
)
The zip file will be generated in the current CMake binary dir (CMAKE_CURRENT_BINARY_DIR
).

I assume you already have a zip-tool installed (WinZip or 7z, etc.). You could write a find_zip-tool script which will search for WinZip, or 7Z, etc...
Snippet for WinZip:
FIND_PROGRAM(ZIP_EXECUTABLE wzzip PATHS "$ENV{ProgramFiles}/WinZip")
IF(ZIP_EXECUTABLE)
SET(ZIP_COMMAND "\"${ZIP_EXECUTABLE}\" -P \"<ARCHIVE>\" @<FILELIST>")
ENDIF(ZIP_EXECUTABLE)
Snippet for 7-zip:
FIND_PROGRAM(ZIP_EXECUTABLE 7z PATHS "$ENV{ProgramFiles}/7-Zip")
IF(ZIP_EXECUTABLE)
SET(ZIP_COMMAND "\"${ZIP_EXECUTABLE}\" a -tzip \"<ARCHIVE>\" @<FILELIST>")
ENDIF(ZIP_EXECUTABLE)
Take a look at the file
<cmake-install-dir>\share\cmake-2.8\Modules\CPackZIP.cmake
it shows how CPack searches for a Zip_Executable and prepares some "useful" default flags.
After that, I would suggest to execute_process, similar to sakra's answer

It's never late to show real answer:
function(create_zip output_file input_files working_dir)
add_custom_command(
COMMAND ${CMAKE_COMMAND} -E tar "cf" "${output_file}" --format=zip -- ${input_files}
WORKING_DIRECTORY "${working_dir}"
OUTPUT "${output_file}"
DEPENDS ${input_files}
COMMENT "Zipping to ${output_file}."
)
endfunction()
Use like
file(GLOB ZIP_FILES "${CMAKE_CURRENT_SOURCE_DIR}/zip/*")
create_zip("${CMAKE_CURRENT_BINARY_DIR}/native_data.zip" "${ZIP_FILES}" "${CMAKE_CURRENT_SOURCE_DIR}/zip")
This will pack all files from zip/
subdirectory into native_data.zip
(in build directory). Then either include your archive (path will differ in different CMakeLists.txt
!) as source file or add it as target:
add_custom_target("project-data" ALL DEPENDS "${CMAKE_CURRENT_BINARY_DIR}/native_data.zip")
Install will not differ a lot from usual:
install(FILES "${CMAKE_CURRENT_BINARY_DIR}/native_data.zip" DESTINATION ${DATADIR} RENAME "data000.zip") # Install our zip (as data000.zip)

Essentially what I did was create custom target
add_custom_target(STAGE_FILES)
With this target I copy the files and directories to the CMAKE_CURRENT_BINARY_DIR
add_custom_command(
TARGET STAGE_FILES
COMMAND ${CMAKE_COMMAND} -E copy_directory ${CMAKE_SOURCE_DIR}/assets/video ${CMAKE_CURRENT_BINARY_DIR}/video
COMMAND ${CMAKE_COMMAND} -E copy_directory ${CMAKE_SOURCE_DIR}/assets/data ${CMAKE_CURRENT_BINARY_DIR}/data
COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_SOURCE_DIR}/assets/strings_en.csv ${CMAKE_CURRENT_BINARY_DIR}/
COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_SOURCE_DIR}/assets/strings_rules_en.csv ${CMAKE_CURRENT_BINARY_DIR}/
COMMAND ${CMAKE_COMMAND} -E tar "cfv" "data.zip" --format=zip --files-from=${CMAKE_SOURCE_DIR}/assets/to_zip.txt
COMMAND ${CMAKE_COMMAND} -E remove_directory ${CMAKE_CURRENT_BINARY_DIR}/data
COMMAND ${CMAKE_COMMAND} -E rename ${CMAKE_CURRENT_BINARY_DIR}/data.zip ${CMAKE_CURRENT_BINARY_DIR}/data
)
The important line
COMMAND ${CMAKE_COMMAND} -E tar "cfv" "data.zip" --format=zip --files-from=${CMAKE_SOURCE_DIR}/assets/to_zip.txt
inside my
to_zip.txt
I specify all the files I want to include in my zip
data/
video/
...
I can now execute the command
make STAGE_FILES
which will copy and zip everything i need
