I am using cmake to configure my project. I visualize project's files using qtcreator which read the CMakeLists.txt. I have a few text files (non-code: config files, log, ..) and I would like to add them to my cmake project without (of course) compiling/linking them. Is it possible ? The main goal it to open them automatically in the tree of my project with qtcreator and edit them ... Thanks for help.

You should be able to just add them to your list of sources in whichever add_executable or add_library call is appropriate and they will appear in the IDE.

I believe CMake uses the files' extensions to determine if they are actual source files, so if yours have extensions like ".txt" or ".log" they won't be compiled.

Hi I've created this kind of function:

cmake_minimum_required(VERSION 3.5)
# cmake_parse_arguments needs cmake 3.5

##
# This function always adds sources to target, but when "WHEN" condition is not meet
# source is excluded from build process.
# This doesn't break build, but source is always visible for the project, what is 
# very handy when working with muti-platform project with sources needed
# only for specific platform
#
# Usage:
#      target_optional_sources(WHEN <condition> 
#                              TARGET <target>
#                              <INTERFACE|PUBLIC|PRIVATE> [items2...]
#                              [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])
##
function(target_optional_sources)
    set(options OPTIONAL "")
    set(oneValueArgs WHEN TARGET)
    set(multiValueArgs PUBLIC PRIVATE INTERFACE)

    cmake_parse_arguments(target_optional_sources 
                          "${options}" "${oneValueArgs}" "${multiValueArgs}"
                          ${ARGN})

    target_sources(${target_optional_sources_TARGET}
                   PUBLIC ${target_optional_sources_PUBLIC}
                   PRIVATE ${target_optional_sources_PRIVATE}
                   INTERFACE ${target_optional_sources_INTERFACE})

    if (NOT ${target_optional_sources_WHEN})

        set_source_files_properties(${target_optional_sources_PUBLIC}
                                    PROPERTIES HEADER_FILE_ONLY TRUE)
        set_source_files_properties(${target_optional_sources_PRIVATE}
                                    PROPERTIES HEADER_FILE_ONLY TRUE)
        set_source_files_properties(${target_optional_sources_INTERFACE}
                                    PROPERTIES HEADER_FILE_ONLY TRUE)

    endif(NOT ${target_optional_sources_WHEN})

endfunction(target_optional_sources)

On one hand it works as it is desired, on other hand some error is reported, so still working on that. Issu turn out to be problem how I used the function not how it is written. Now it works perfectly.

Instead of adding files which are not directly needed to build your library or executable, you can create a custom target to make these files appear in you IDE:

add_custom_target(myapp-doc
    SOURCE readme.txt)
