qt - How to convert qmake to cmake?

Question

I have a .pro file on my project, but now I want to port it to a CMakeLists.txt file. How can I do this?

QT += core
QT -= gui
CONFIG += c++11
TARGET = test
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
QT += network
SOURCES += main.cpp 
    test_interface.cpp 
    motomanlibrary.cpp 
    processing.cpp
SOURCES += main.cpp 
    test_interface.h 
    motomanlibrary.h 
    processing.h

Answer 1

QMake: The required libraries.

QT += core
QT -= gui
QT += network

CMake: only the add is necessary. An exclude (QT -= gui) is not required.

find_package(Qt5Core REQUIRED)
find_package(Qt5Network REQUIRED)

QMake: Additional Compiler flags:

CONFIG += c++11

CMake: Extend the list of compiler flags as required.

set(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -std=c++0x")

QMake: The source files

SOURCES += main.cpp 
    test_interface.cpp 
    motomanlibrary.cpp 
    processing.cpp

CMake: Create a list of source files

set(SOURCES
    main.cpp
    test_interface.cpp
    motomanlibrary.cpp
    processing.cpp
)

QMake: The header to be included:

SOURCES += main.cpp 
    test_interface.h 
    motomanlibrary.h 
    processing.h

CMake: Just show where the header files are.

include_directory(.) #  or include_directory(${CMAKE_CURRENT_SOURCE_DIR})
include_directory(some/where/else)

QMake: The target to be built:

TARGET = test

CMake: Set the name of the target, add the sources, link the required libs.

add_executable(test ${SOURCES} )
qt5_use_modules(test Core Network) # This macro depends from the Qt version

# Should not be necessary
#CONFIG += console
#CONFIG -= app_bundle
#TEMPLATE = app
