| # Example (JKQTPlotter): CMake FetchContent Example {#JKQTCMakeFetchContentExample} | ||
|
|
||
| This project (see [`cmake_fetchcontent_example`](https://github.com/jkriege2/JKQtPlotter/tree/master/examples/cmake_fetchcontent_example) demonstrates how to link against JKQTPlotter using CMake's [FetchContent-API](https://cmake.org/cmake/help/latest/module/FetchContent.html). Also have a look at [this blog post](https://www.foonathan.net/2022/06/cmake-fetchcontent/) for a detailed explanation. See https://jkriege2.github.io/JKQtPlotter/page_buildinstructions__c_m_a_k_e.html for details on how to build JKQTPlotter with CMake | ||
|
|
||
| This example uses very simple code, which simply displays a plotter and shows some data. The important part of this example is the ´CMakeLists.txt`-file: | ||
| ``` | ||
| # set minimum required CMake-Version | ||
| cmake_minimum_required(VERSION 3.23) | ||
| # set Project name | ||
| project(simpletest_cmake LANGUAGES CXX) | ||
| # some basic configurations | ||
| set(CMAKE_AUTOMOC ON) | ||
| set(CMAKE_INCLUDE_CURRENT_DIR ON) | ||
| # Configure project for usage of Qt5/Qt6 | ||
| find_package(QT NAMES Qt6 Qt5 COMPONENTS Core Gui Widgets PrintSupport Svg Xml OpenGl REQUIRED) | ||
| find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core Gui Widgets PrintSupport Svg Xml OpenGL REQUIRED) | ||
| # include JKQTPlotter via FetchContent-API: | ||
| # ... first load the FetchContent-API: | ||
| include(FetchContent) # once in the project to include the module | ||
| # ... now declare JKQTPlotter5/6 | ||
| FetchContent_Declare(JKQTPlotter${QT_VERSION_MAJOR} | ||
| GIT_REPOSITORY https://github.com/jkriege2/JKQtPlotter.git | ||
| # GIT_TAG v5.0.0) | ||
| # ... finally make JKQTPlotter5/6 available | ||
| FetchContent_MakeAvailable(JKQTPlotter${QT_VERSION_MAJOR}) | ||
| # For Visual Studio, we need to set some additional compiler options | ||
| if(MSVC) | ||
| add_compile_options(/EHsc) | ||
| # To enable M_PI, M_E,... | ||
| add_definitions(/D_USE_MATH_DEFINES) | ||
| # To Prevent Errors with min() and max() | ||
| add_definitions(/DNOMINMAX) | ||
| # To fix error: C2338: va_start argument must not | ||
| # have reference type and must not be parenthesized | ||
| add_definitions(/D_CRT_NO_VA_START_VALIDATION) | ||
| endif() | ||
| # add the example executable | ||
| add_executable(${PROJECT_NAME} WIN32 simpletest.cpp) | ||
| # ... link against Qt5/6 and JKQTPlotterLib | ||
| # (you could use JKQTPlotterSharedLib if you don't want to link againast the | ||
| # static version, but against the shared/DLL version). | ||
| target_link_libraries(${PROJECT_NAME} PUBLIC Qt${QT_VERSION_MAJOR}::Core Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Gui Qt${QT_VERSION_MAJOR}::PrintSupport Qt${QT_VERSION_MAJOR}::Svg Qt${QT_VERSION_MAJOR}::Xml) | ||
| # ... link against JKQTPlotter: As the Targets contain the Qt-Version-Number in their names, we can | ||
| # link against 'JKQTPlotter${QT_VERSION_MAJOR}::JKQTPlotter${QT_VERSION_MAJOR}' and it works | ||
| # for Qt5 AND Qt6 ... | ||
| # if you have a speific Qt-Version, you can also write e.g. 'JKQTPlotter6::JKQTPlotter6' | ||
| target_link_libraries(${PROJECT_NAME} PUBLIC JKQTPlotter${QT_VERSION_MAJOR}::JKQTPlotter${QT_VERSION_MAJOR}) | ||
| # Installation | ||
| install(TARGETS ${PROJECT_NAME} | ||
| RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR} | ||
| ) | ||
| ``` | ||
|
|
||
| The important steps here are | ||
| ``` | ||
| include(FetchContent) # once in the project to include the module | ||
| # ... now declare JKQTPlotter5/6 | ||
| FetchContent_Declare(JKQTPlotter${QT_VERSION_MAJOR} | ||
| GIT_REPOSITORY https://github.com/jkriege2/JKQtPlotter.git | ||
| # GIT_TAG v5.0.0) | ||
| # ... finally make JKQTPlotter5/6 available | ||
| FetchContent_MakeAvailable(JKQTPlotter${QT_VERSION_MAJOR}) | ||
| ``` | ||
|
|
||
| where JKQTPlotter is first declared to the FetchContent-API and then loaded. | ||
|
|
||
|
|
||
| To build this example, you first need to make a subdirectory `build` and then call CMake form that subdirectory: | ||
| ```.sh | ||
| $ mkdir build | ||
| $ cd build | ||
| $ cmake .. -G "<GENERATOR>" "-DCMAKE_PREFIX_PATH=<path_to_your_qt_sources>" | ||
| cmake --build . --config "Debug" | ||
| ``` | ||
| In the configure step above, you need to specify the directory `<path_to_your_qt_sources>` of yout Qt installation and the `<GENERATOR>` appropriate for you use-case. | ||
