Update libressl rules for options api type, add some docs to build, use CHECK_SYMBOL_EXISTS since CHECK_FUNCTION_EXISTS is fooled by the conditionals in the headers

## Background
|
|
|
|
libressl is another fork of Openssl.
|
|
|
|
## Example build for libressl itself
|
|
|
|
If you unpack or clone into `/path/to/libressl` and enter that dir...
|
|
|
|
```
|
|
$ mkdir build
|
|
$ cd build
|
|
$ cmake ..
|
|
$ make -j8
|
|
```
|
|
|
|
## Example build for lws against libressl
|
|
|
|
You can just build lws as you would for a specific version of openssl
|
|
|
|
```
|
|
$ mkdir build
|
|
$ cd build
|
|
$ cmake .. -DLWS_OPENSSL_LIBRARIES='/path/to/libressl/build/tls/libtls.a;/path/to/libressl/build/ssl/libssl.a;/path/to//libressl/build/crypto/libcrypto.a' -DLWS_OPENSSL_INCLUDE_DIRS=/path/to/libressl/include -DLWS_WITH_MINIMAL_EXAMPLES=1
|
|
$ make -j8
|
|
```
|
|
|
|
Libressl by default will look for a trust bundle in `/usr/local/etc/ssl/cert.pem`, you either have to
|
|
symlink this to your trust bundle if that doesnt happen to be where it is, or give your app the trusted CA
|
|
specifically as is done for MBEDTLS and WOLFSSL in the examples.
|
|
|
|
In Fedora, the system trust store can be found at `/etc/pki/tls/cert.pem`, so you can symlink it
|
|
|
|
```
|
|
$ sudo mkdir -p /usr/local/etc/ssl
|
|
$ sudo ln -sf /etc/pki/tls/cert.pem /usr/local/etc/ssl/cert.pem
|
|
```
|
|
|
|
after that you can run examples from the build dir, eg,
|
|
|
|
```
|
|
