Adding Qt UI files to your CMake

Qt uses qmake to generate classes from UI files and compile everything in the project, luckily there are some macros in CMake that allows you to bring everything into your CMake and build everything there, here is what you need to do:

cmake_minimum_required (VERSION 2.8.12)
project (Qt5CMake)

find_package (Qt5Widgets)

set (MyProjectLib_src ${PROJECT_SOURCE_DIR}/src/mainwindow.cpp)
set (MyProjectLib_hdr ${PROJECT_SOURCE_DIR}/include/mainwindow.h)
set (MyProjectLib_ui  ${PROJECT_SOURCE_DIR}/UI/mainwindow.ui)
set (MyProjectBin_src ${PROJECT_SOURCE_DIR}/src/main.cpp)

qt5_wrap_cpp(MyProjectLib_hdr_moc ${MyProjectLib_hdr})
qt5_wrap_ui (MyProjectLib_ui_moc  ${MyProjectLib_ui})

include_directories (${PROJECT_SOURCE_DIR})
include_directories (${PROJECT_BINARY_DIR})

add_library (MyProjectLib SHARED 
    ${MyProjectLib_src}
    ${MyProjectLib_hdr_moc}
    ${MyProjectLib_ui_moc}
)
target_link_libraries (MyProjectLib Qt5::Widgets)

add_executable(MyProject ${MyProjectBin_src})
target_link_libraries (MyProject MyProjectLib)

cmake_minimum_required (VERSION 2.8.12)

project (Qt5CMake)

find_package (Qt5Widgets)

set (MyProjectLib_src ${PROJECT_SOURCE_DIR}/src/mainwindow.cpp)

set (MyProjectLib_hdr ${PROJECT_SOURCE_DIR}/include/mainwindow.h)

set (MyProjectLib_ui ${PROJECT_SOURCE_DIR}/UI/mainwindow.ui)

set (MyProjectBin_src ${PROJECT_SOURCE_DIR}/src/main.cpp)

qt5_wrap_cpp(MyProjectLib_hdr_moc ${MyProjectLib_hdr})

qt5_wrap_ui (MyProjectLib_ui_moc ${MyProjectLib_ui})

include_directories (${PROJECT_SOURCE_DIR})

include_directories (${PROJECT_BINARY_DIR})

add_library (MyProjectLib SHARED

${MyProjectLib_src}

${MyProjectLib_hdr_moc}

${MyProjectLib_ui_moc}

)

target_link_libraries (MyProjectLib Qt5::Widgets)

add_executable(MyProject ${MyProjectBin_src})

target_link_libraries (MyProject MyProjectLib)

Send CMake param to catkin

Leave a Comment / C++, ROS, Tutorials / admin

It quite often happens that you need to send a CMake parameter to your catkin project, for instance, you need to build your code for debugging mode. The correct syntax is:

catkin_make  -DCMAKE_BUILD_TYPE="Release"

1	catkin_make -DCMAKE_BUILD_TYPE="Release"

another example:

catkin_make -DCMAKE_VERBOSE_MAKEFILE=ON

1	catkin_make -DCMAKE_VERBOSE_MAKEFILE=ON

pkg-config and CMake

Leave a Comment / C++, Tutorials / admin

pkg-config and CMake If the library that you want to use is not coming with Find<package>. cmake you can use pkg-config files which are stored in “.pc”. The environmental variable PKG_CONFIG_PATH is the place that should point to the “.pc” files. Type in the shell:

PKG_CONFIG_PATH=<path-to-directory-containing-the-.pc-file>:${PKG_CONFIG_PATH}
export PKG_CONFIG_PATH
printenv PKG_CONFIG_PATH

PKG_CONFIG_PATH=<path-to-directory-containing-the-.pc-file>:${PKG_CONFIG_PATH}

export PKG_CONFIG_PATH

printenv PKG_CONFIG_PATH

To get the list of all available package configs, you can

How to find CMake from arbitrary installed locations

Leave a Comment / C++, Tutorials / admin

In my other tutorial, I showed you how to install your code in an arbitrary location in Unix/ Linux systems. In this tutorial, I’m gonna show you how to find them after installation. Here I have two examples: OpenCV, PCL point cloud I can assume that you have compiled and installed them using the following command:

cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX:PATH=~/usr .. && make -j8 all install

1	cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX:PATH=~/usr .. && make -j8 all install

1)PCL

Installing programs into arbitrary location in Unix/ Linux systems

1 Comment / C++, Tutorials / admin

After you compiled and built your code, you should install it by calling sudo install to put headers and shared libraries into /usr/include/ and /usr/lib/ and configuration files into /usr/local and /usr/share usually, I don’t like to touch my system binaries and I prefer to install my compiled code into my home directory so I can safely delete them anytime. If you using
