CMake → После сборки CMake windeployqt собирает debug-библиотеки
Ещё раз здравствуйте.
Собираю Qt-проект с помощью CMake. Применяю к полученному exe-файлу windeployqt. В результате подцепляются почему-то dll-ки, оканчивающиеся в наименованиях на "d": Qt5Cored.dll, Qt5Guid.dll и т.д. Собирал тем не менее релизную сборку.

CMake → Как подключить в CMakeList.txt папку с исходниками?
Добрый день.
В исходниках подключаю заголовочный файл:
#include "../../src/database.h"
Как теперь его подключить в CMakeList.txt ?
Делаю так:
include_directories(../../src)
Компилятор всё равно ругается на неопределённые переменные, которые указаны в …

CMake → Не получить значение переменной из CMakeList.txt
Попробовал сделать пример по статье: Использование переменных объявленных в CMakeLists.txt внутри C++ файлов с помощью Qt Creator. Копилятор в ответ пишет: "'PROJECT_NAME' was not declared in this scope", "'SOFT_VERSION' was not declared in this scope".

CMake → Using variables declared in CMakeLists.txt inside C ++ files
I propose to consider the option of using variables declared in the CMakeLists.txt file in C ++ code.
To begin with, what is it for? For example, you want to specify the version of the program and some other auxiliary information that is set during the assembly of the program, but at the same time you want to use this information in your C ++ code? Is it possible to do this? For example, to make it look like the image shows.

CMake → Как получить значение переменной из CMakeLists.txt
Всем привет!
У меня в CMakeLists.txt указывается версия софта:
cmake_minimum_required(VERSION 3.8)
project(my_project_name)
set (VERSION_MAJOR 0)
set (VERSION_MINOR 1)
set (VERSION_PATCH 0)
set (SOFT_VERSION ${VERSION_MAJOR}.${VERSION_MINOR}.${VERSION_PATCH})

XOR-encryption is the application of a key through bitwise exclusive OR to the source text. The mechanism of the bitwise exclusive is the following:
| X | Y | X⊕Y |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Thus, when executing an exclusive OR, there will always be a zero value if the variables have the same values.
The peculiarity of XOR is that one and the same function can both encrypt data and decrypt it. This is a simple method of data encryption, which can be hacked quickly enough if there is a large enough encrypted text, or a large password dictionary. But nevertheless, this can already be used for small initial data protection.
In the context of Qt, the use of XOR is no different from how the program was written without using Qt. The question here is how to extract data for encryption from QString objects, for example, if the text was entered in QTextEdit.
To do this, write a program that contains:
- QTextEdit, In which the text will be entered, which will be encrypted.
- QLineEdit, In which the encryption key will be entered.
- QPushButton, In the slot of the click handler of which, data encryption / decryption will be performed. Again, I note that the method will be used the same.
The program will look like this:
Qt → Qt/C++ - Tutorial 068. Hello World using the CMAKE build system in CLion
Write "Hello, World !!!" On Qt in the IDE CLion using the CMAKE build system. The emphasis on the fact that the project is being developed in IDE CLion was made because to work with the project it is necessary to make a small adjustment for working with CMAKE .
The result is the following application:
