cmake for OpenDDS Project - build

looking for a standard CMakelist to build OpenDDS application (Simple Publisher/Subscriber). I am familiar with the Tutorials and everything is running fine with MPC to build the examples. I need to build my project with cmake. I m using OpenDDS 3.9.
I tried to make a CMakelist for the Stockquote Example on here:
http://opendds.org/about/articles/Article-Intro.html
My CMakelist looks as follows:
cmake_minimum_required (VERSION 3.3.0)
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
project (publisher)
set(DDS_ROOT_DIR "home/ubuntu/OpenDDS-3.9")

I got the adding DDS Link Libraries Section from the WTeam Blog. http://www.wteam.it/index.php/articles/the-hla-series/9-article/15-first-opendds-program
Currently i receive this error message if i'm using cmake --build:

Does anyone have an idea whats wrong or has a standard CMake for OpenDDS applications? Thank you very much for any help.

OpenDDS 3.14 will have cmake support, see https://github.com/objectcomputing/OpenDDS/tree/master/tests/cmake_integration for unit tests using cmake.

The example project on that website is bundled with OpenDDS under the 'examples/DCPS' folder. It contains a working build script, instructions etc.

Cmake exe file just run in my system in Sunshine project [terminate called after throwing an instance of std::filesystem::__cxx11::filesystem_error]

I want to create one .exe file from the Sunshine GitHub program, I'm new to Cmake and I build that program with its help
git clone https://github.com/loki-47-6F-64/sunshine.git --recursive
cd sunshine && mkdir build && cd build
cmake -G"Unix Makefiles" ..
mingw32-make
It builds and runs correctly and creates .exe, but works only in my system.
On other systems, it gets filesystem errors and shows the path of the system that I build it:
terminate called after throwing an instance of
'std::filesystem::__cxx11::filesystem_error' what(): filesystem

I think in this file something makes this issue but I don't know.
This is its release file that works correctly and doesn't have my issue:
https://github.com/loki-47-6F-64/sunshine/releases/download/v0.9.0/Sunshine-Windows.zip
How can I create like this?
I fixed My problem by running CMake with one additional parameter.
cmake -G "Unix Makefiles" -DSUNSHINE_ASSETS_DIR=assets ..
exe program needs to know assets and also after that assets folder should be near the exe file like a programmer release.

CLion: Could not find a configuration file for package "Qt6" that is compatible with requested version ""

Here is a picture of the MinGW configuration in Toolchains
From Qt 6 documenation:
For find_package to be successful, CMake must find the Qt installation. There are different ways you can tell CMake about Qt:
Set the CMAKE_PREFIX_PATH environment variable to include the Qt 6 installation prefix.
Set the CMake cache variable CMAKE_PREFIX_PATH to include the Qt 6 installation prefix.
For example, following code is needed:
set(CMAKE_PREFIX_PATH "D:/SDK/Qt/6.0.1/msvc2019_64/lib/cmake/")

CMAKE + SQLite3.dll

Anyone know how to copy the SQLite3.dll into the executable directory using CMAKE? I am able to use sqlite in generated VS project but when i try to run the exe it cannot find the dll.
I am guessing that CMAKE would write a copy command into the post-build events in the VS project settings? But how is that done through CMAKE.

Deploy icu libraries when linking a cmake project with Qt5

I've the following CMakeLists.txt for creating a little application:
cmake_minimum_required (VERSION 3.5.0)
project (sampleapp)
# Setting project flags
set (CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/build/lib)
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/build/lib)

file (GLOB_RECURSE PROJECT_SRC *.cpp)
# Creating project
add_executable(${PROJECT_NAME} ${PROJECT_SRC})
# Linking dependencies
target_link_libraries (${PROJECT_NAME} somelibrary Qt5::Widgets Qt5::Gui Qt5::Core)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy_if_different $<TARGET_FILE:Qt5::Widgets> $<TARGET_FILE_DIR:${PROJECT_NAME}>)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy_if_different $<TARGET_FILE:Qt5::Gui> $<TARGET_FILE_DIR:${PROJECT_NAME}>)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy_if_different $<TARGET_FILE:Qt5::Core> $<TARGET_FILE_DIR:${PROJECT_NAME}>)
When I run it and then build the application the Qt dlls are copied into target folder. In particular I copy:
Qt5Core.dll
Qt5Gui.dll
Qt5Widgets.dll
When I run the application it does not start anyway because the ICU libraries needed for Qt are not copied. When I start the application, Windows tells me that following libraries are missing:
icuin53.dll
icuuc53.dll
If I copy these libraries manually from Qt insallation folder it works (ok, I've an error regarding "platform plugins windows" missing but it's another story).
Is there a way to copy the icu libraries in a standard way, like the post build commands that I'm using for copying libraries? Or what's the best way to copy them in a transparent way, if possible (CMake can know what are dependencies of Qt and copy them where Qt are needed)?
Instead of copying each dll by hand, you can install all Qt dependencies using windeployqt, the tool provided with Qt for deployment on Windows.
You can first declare windeployqt as an imported executable:
find_package(Qt5
# ...
)
if(Qt5_FOUND AND WIN32 AND TARGET Qt5::qmake AND NOT TARGET Qt5::windeployqt)
get_target_property(_qt5_qmake_location
Qt5::qmake IMPORTED_LOCATION
)
execute_process(
COMMAND "${_qt5_qmake_location}" -query QT_INSTALL_PREFIX
RESULT_VARIABLE return_code
OUTPUT_VARIABLE qt5_install_prefix
OUTPUT_STRIP_TRAILING_WHITESPACE
)
set(imported_location "${qt5_install_prefix}/bin/windeployqt.exe")
if(EXISTS ${imported_location})
add_executable(Qt5::windeployqt IMPORTED)
set_target_properties(Qt5::windeployqt PROPERTIES
IMPORTED_LOCATION ${imported_location}
)
endif()
endif()
Now the imported executable can be used as follows:
add_executable(foo
# ...
)
if(TARGET Qt5::windeployqt)
add_custom_command(TARGET foo
POST_BUILD
COMMAND ${CMAKE_COMMAND} -E remove_directory "${CMAKE_CURRENT_BINARY_DIR}/windeployqt"
COMMAND set PATH=%PATH%$<SEMICOLON>${qt5_install_prefix}/bin
COMMAND Qt5::windeployqt --dir "${CMAKE_CURRENT_BINARY_DIR}/windeployqt" "$<TARGET_FILE:foo>"
)
install(
DIRECTORY
"${CMAKE_CURRENT_BINARY_DIR}/windeployqt/"
DESTINATION ${FOO_INSTALL_RUNTIME_DESTINATION}
)
endif()

include_directories and CMAKE_INSTALL_FULL_INCLUDEDIR

I am building two C++ libraries(2 CMake projects). library2 depends on library1. I am installing my first library header files at ${CMAKE_INSTALL_INCLUDEDIR}/mylibraries. Now to include library1 header files in my library2, I am doing include_directories(${CMAKE_INSTALL_FULL_INCLUDEDIR}/mylibraries) in the library2's CMakeLists.txt.
But the make is failing with no such file or directory error.
