Okay, I think I (might) know what's going wrong here:
"FindOpenSSL.cmake" line ~303
Here, a regex match attempts to extract the version number from "openssl/opensslv.h". Inside the header, it seraches for:
#define OPEN_SSL_VERSION <value>
Investigating, it appears some versions of OpenSSL (perhaps newer ones), this fails. In my header, the "OPEN_SSL_VERSION" is defined as a combination of macros.
The regex expects something like this:
#define OPEN_SSL_VERSION 12345
However, it instead encounters this:
# define OPENSSL_VERSION_NUMBER \
( (OPENSSL_VERSION_MAJOR<<28) \
|(OPENSSL_VERSION_MINOR<<20) \
|(OPENSSL_VERSION_PATCH<<4) \
|_OPENSSL_VERSION_PRE_RELEASE )
Consequently, the extracted version number ends up being empty.
(Note: I am using OPENSSL_VERSION_STR "3.1.3")
PS: I've hack-fixed this locally by modifying the "opensslv.h" header via:
# define OPENSSL_VERSION_NUMBER 0x30100030L // version, in hex value
/*# define OPENSSL_VERSION_NUMBER \
( (OPENSSL_VERSION_MAJOR<<28) \
|(OPENSSL_VERSION_MINOR<<20) \
|(OPENSSL_VERSION_PATCH<<4) \
|_OPENSSL_VERSION_PRE_RELEASE )
*/
... not the best, but it looks like things are building now.
You need to specify where it can get the version from:
Change your cmake to this:
include("cmake/HunterGate.cmake")
HunterGate(
URL "https://github.com/cpp-pm/hunter/archive/v0.23.297.tar.gz"
SHA1 "3319fe6a3b08090df7df98dee75134d68e2ef5a3"
LOCAL
)
project(sync_db_cpp LANGUAGES CXX)
hunter_add_package(libp2p)
find_package(libp2p REQUIRED)
(add the local keyword in HunterGate to specify locally where huntergate can get the packages).
Then add a config.cmake in a Hunter folder, which should be in the same folder as your HunterGate.cmake (so cmake/Hunter/config.cmake for you) and write:
message("Loading CMAKE\n\n\n\n\n\n\n")
hunter_config(
GTest
VERSION 1.8.0-hunter-p11
)
hunter_config(sr25519

This fixed it for me (might have to play with the hashes a bit, as in the SHA1 value). Also this for me fixed the issue above BUT lead me into another list of issues, which I can't even fix.
