QMakeToCMake

Helper script to move qmake (Qt5) based subdirs/project to cmake

Warning: its not bullet proof, main goal is too speed up manual operation

will be usefull if lots of pro file to convert

Features:

• TEMPLATE=subdirs, you may need to re-order add_subdirectoies lines

• TEMPLATE=app

• TEMPLATE=lib

• TARGET will name the target

• QT, will add find-packages, target_link_libraries for defined modules

• CMAKE_AUTO_RCC if qrc file defined

• CMAKE_AUTO_uic if .ui files defined

• CMAKE_AUTO_MOC if depends on Qt5Core

• if CONFIG contains c++11, wil add magic lines to enable it on CMakeLists.txt

• CONFIG-=qt , no Qt dependencies

• DEFINES

• INCLUDEPATH

• CONFIG values and custom variable can define new lines on cmakelist.txt with a json config file (see example/config.json)

Examples

libToto.pro:

TEMPLATE=lib
QT += core gui
CONFIG+=c++11
TARGET=Toto
SOURCES=aaa.cpp\
  bbb.cpp\
  ccc.cpp
HEADERS=aaa.h\
  bbb.h\
  ccc.h
FORMS=a.ui
RESOURCES=r.qrc

CMakeLists.txt

make_minimum_required(VERSION 3.0.0 )
project(libToto)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
find_package(Qt5Core)
find_package(Qt5Gui)
set(src a.cpp
        b.cpp
        c.cpp)
set(headers a.h
        b.h
        c.h)
set(resources r.qrc)
set(forms a.ui)
add_library(Toto ${src} ${headers} ${resources} ${forms})
target_link_libraries(Toto PRIVATE Qt5::Core Qt5::Gui)
set_target_properties(Toto PROPERTIES DEBUG_POSTFIX "d")
install(TARGETS Toto DESTINATION Libs)

Limitations

q2c does not read correctly conditionnal blocks:
CONTAINS(CONFIG,featureXXX): QT+= printsupport
will be omited during parse

CONTAINS(CONFIG,featureXXX){
blockIf
}else{
blockElse
}
blockIf AND blockElse will be parsed 

Usage:

download or clone

cd to QMakeToCMake

pip install .
# will install commandline app named 'q2c'

usage: q2c [-h] [-n] [-r] [-s] [-c] path

positional arguments:
  path             directory or file

optional arguments:
  -h, --help       show this help message and exit
  -n, --dry-run    print conversion on the console
  -r, --recursive  all .pro in directory tree
  -s, --show       show result file(s) , use it with recursive option to survey operations
  -s, --config     json file defining dictionnary between CONFIG values in .pro file and cmake function
