Changes include: * Rename CMakeLists.txt to android_openssl.cmake * Move the CMake code into a function android_add_openssl_to_targets(), so that the caller can decide what targets get the OpenSSL libs * update README

# Android OpenSSL support for Qt
|
|
OpenSSL scripts and binaries for Android (useful for Qt Android apps)
|
|
|
|
In this repo you can find the prebuilt OpenSSL libs for Android, a QMake include project `.pri` file that can be used integrated with Qt projects, and a `.cmake` file for CMake based projects.
|
|
|
|
The following directories are available
|
|
* `ssl_3`: used for Qt 6.5.0+.
|
|
* `ssl_1_1`: for Qt Qt 5.12.5+, 5.13.1+, 5.14.0+, 5.15.0+, Qt 6.x.x up to 6.4.x
|
|
|
|
## How to use it
|
|
### QMake based projects
|
|
To add OpenSSL to your QMake project, append the following to your `.pro` project file:
|
|
|
|
```
|
|
android: include(<path/to/android_openssl/openssl.pri)
|
|
```
|
|
|
|
### CMake based projects
|
|
To add OpenSSL to your CMake project, append the following to your project's `CMakeLists.txt` file:
|
|
|
|
```
|
|
if (ANDROID)
|
|
FetchContent_Declare(
|
|
android_openssl
|
|
DOWNLOAD_EXTRACT_TIMESTAMP true
|
|
URL https://github.com/KDAB/android_openssl/archive/refs/heads/master.zip
|
|
# URL_HASH MD5=c97d6ad774fab16be63b0ab40f78d945 #optional
|
|
)
|
|
FetchContent_MakeAvailable(android_openssl)
|
|
include(${android_openssl_SOURCE_DIR}/android_openssl.cmake)
|
|
endif()
|
|
```
|
|
or, if you cloned the repository into a subdirectory:
|
|
|
|
```
|
|
include(<path/to/android_openssl>/android_openssl.cmake)
|
|
```
|
|
|
|
Then
|
|
|
|
```
|
|
qt_add_executable(your_target_name ..)
|
|
qt_add_executable(your_second_target_name ..)
|
|
|
|
if (ANDROID)
|
|
add_android_openssl_libraries(your_target_name your_second_target_name)
|
|
endif()
|
|
|
|
```
|
|
|
|
## Build Script
|
|
|
|
The build script `build_ssl.sh` can be used to rebuild the OpenSSL libraries. Since specific
|
|
versions might depend or work better with specific NDK versions, the OpenSSL<==>NDK version
|
|
combinations are defined in the script. Before running the script, check that the NDK paths
|
|
are correct for your environment.
|
|
|
|
### Build Prerequisites
|
|
|
|
Both Linux, macOS need `patchelf` command when building for OpenSSL 3+.
|
|
|
|
Additionally, for macOS you need:
|
|
- `bash` shell version 4+ is required
|
|
- `wget` command
