### To install QXlsx

Enter the command as shown below.

```sh
mkdir build
cd build
cmake ../QXlsx/ -DCMAKE_INSTALL_PREFIX=... -DCMAKE_BUILD_TYPE=Release
cmake --build .
cmake --install .
```

### To use in your application

In your CMakeLists.txt:

```cmake
find_package(QXlsxQt5 REQUIRED) # or QXlsxQt6
target_link_libraries(myapp PRIVATE QXlsx::QXlsx)
```

### To use in your application without installation

There are 2 possible ways:

1) Use cmake subdirectory
In your CMakeLists.txt:

```cmake
add_subdirectory(QXlsx)
target_link_libraries(myapp PRIVATE QXlsx::QXlsx)
```

2) Use cmake FetchContent
In your CMakeLists.txt:

```cmake
FetchContent_Declare(
  QXlsx
  GIT_REPOSITORY https://github.com/QtExcel/QXlsx.git
  GIT_TAG        sha-of-the-commit
  SOURCE_SUBDIR  QXlsx
)
FetchContent_MakeAvailable(QXlsx)
target_link_libraries(myapp PRIVATE QXlsx::QXlsx)
```

if `QT_VERSION_MAJOR` is not set, QXlsx's CMakeLists.txt will try to find a Qt version (5 or 6) itself.
