### Basic CMakeLists.txt Configuration

Source: https://github.com/nxp/plug-and-trust/blob/master/ecc_example/CMakeLists.txt

Sets up the minimum CMake version, project name, and includes a library definition file.

```cmake
CMAKE_MINIMUM_REQUIRED(VERSION 3.5.0)


project (ex_ecc)

SET(SIMW_LIB_DIR ${CMAKE_CURRENT_SOURCE_DIR}/..)
INCLUDE(${SIMW_LIB_DIR}/simw_lib.cmake)
```

--------------------------------

### Configure SE05x Authentication

Source: https://github.com/nxp/plug-and-trust/blob/master/README.rst

Select the authentication method for connecting to the SE Applet. Ensure PTMW_HostCrypto is set to Openssl when using authentication.

```bash
-DPTMW_SE05X_Auth=None
```

```bash
-DPTMW_SE05X_Auth=UserID
```

```bash
-DPTMW_SE05X_Auth=PlatfSCP03
```

```bash
-DPTMW_SE05X_Auth=AESKey
```

```bash
-DPTMW_SE05X_Auth=ECKey
```

```bash
-DPTMW_SE05X_Auth=UserID_PlatfSCP03
```

```bash
-DPTMW_SE05X_Auth=AESKey_PlatfSCP03
```

```bash
-DPTMW_SE05X_Auth=ECKey_PlatfSCP03
```

--------------------------------

### Open Session APIs for SE05x

Source: https://github.com/nxp/plug-and-trust/blob/master/README.rst

These APIs are used to open a session with the SE05x device. They abstract the necessary actions for establishing a connection. Include 'ex_sss_main_inc.h' for simplified session opening.

```c
sss_status_t ex_sss_boot_connectstring(int argc, const char *argv[], char **pPortName);

    sss_status_t ex_sss_boot_open(ex_sss_boot_ctx_t *pCtx, const char *portName);

    sss_status_t ex_sss_key_store_and_object_init(ex_sss_boot_ctx_t *pCtx);
```

```c
sss_status_t ex_sss_entry(ex_sss_boot_ctx_t *pCtx)
```

--------------------------------

### Configure SE05X Version

Source: https://github.com/nxp/plug-and-trust/blob/master/README.rst

Use this build flag to select the SE05X version. Version 07_00 enables SE051/SE052 features.

```bash
-DPTMW_SE05X_Ver=03_XX
```

```bash
-DPTMW_SE05X_Ver=07_02
```

--------------------------------

### Configure Host Crypto Library

Source: https://github.com/nxp/plug-and-trust/blob/master/README.rst

Specify the cryptographic library to be used on the host. OpenSSL is the currently supported option.

```bash
-DPTMW_HostCrypto=OPENSSL
```

```bash
-DPTMW_HostCrypto=None
```

--------------------------------

### Setting Include Directories

Source: https://github.com/nxp/plug-and-trust/blob/master/ecc_example/CMakeLists.txt

Specifies public include directories for the project, including the parent directory and a SIMW include directory.

```cmake
TARGET_INCLUDE_DIRECTORIES(
    ${PROJECT_NAME}
    PUBLIC
    ../
    ${SIMW_INC_DIR}
    )
```

--------------------------------

### Conditional Library Linking for OpenSSL

Source: https://github.com/nxp/plug-and-trust/blob/master/ecc_example/CMakeLists.txt

Links the 'ssl' and 'crypto' libraries to the project if PTMW_HostCrypto is set to OPENSSL.

```cmake
IF("${PTMW_HostCrypto}" STREQUAL "OPENSSL")
    TARGET_LINK_LIBRARIES(${PROJECT_NAME} ssl crypto)
ENDIF()
```

--------------------------------

### Conditional Executable Addition

Source: https://github.com/nxp/plug-and-trust/blob/master/ecc_example/CMakeLists.txt

Adds the main executable, conditionally including authentication sources based on the PTMW_SE05X_Auth variable.

```cmake
IF("${PTMW_SE05X_Auth}" STREQUAL "None")
ADD_EXECUTABLE(${PROJECT_NAME} ${SIMW_SE_SOURCES} ../sss/ex/ecc/ex_sss_ecc.c)
ELSE()
ADD_EXECUTABLE(${PROJECT_NAME} ${SIMW_SE_SOURCES} ${SIMW_SE_AUTH_SOURCES} ../sss/ex/ecc/ex_sss_ecc.c)
ENDIF()
```
